Cerebral Venous Thrombosis in Two Patients with Spontaneous Intracranial Hypotension Thu, 27 Nov 2014 08:24:26 +0000 http://www.hindawi.com/journals/crinm/2014/528268/ Although few patients with spontaneous intracranial hypotension develop cerebral venous thrombosis, the association between these two entities seems too common to be simply a coincidental finding. We describe two cases of spontaneous intracranial hypotension associated with cerebral venous thrombosis. In one case, extensive cerebral venous thrombosis involved the superior sagittal sinus and multiple cortical cerebral veins. In the other case, only a right frontoparietal cortical vein was involved. Several mechanisms could contribute to the development of cerebral venous thrombosis in spontaneous intracranial hypotension. When spontaneous intracranial hypotension and cerebral venous thrombosis occur together, it raises difficult practical questions about the treatment of these two conditions. In most reported cases, spontaneous intracranial hypotension was treated conservatively and cerebral venous thrombosis was treated with anticoagulation. However, we advocate aggressive treatment of the underlying cerebrospinal fluid leak. M. C. Garcia-Carreira, D. Cánovas Vergé, J. Branera, M. Zauner, J. Estela Herrero, E. Tió, and G.

Successful Thrombolysis despite Having an Incidental Unruptured Cerebral Aneurysm Mon, 24 Nov 2014 08:40:27 +0000 http://www.hindawi.com/journals/crinm/2014/323049/ Purpose. To report a case of successful thrombolysis performed in a patient with an incidental unruptured intracranial aneurysm and review the literature. Case Report. Patient admitted for ischemic stroke due to left posterior cerebral artery occlusion, with an incidental right middle cerebral artery aneurysm, who underwent treatment with tissue plasminogen activator (rtPA) resulting in clinical improvement without complications. Conclusion. The presence of unruptured intracranial aneurysms is considered as a contraindication to thrombolysis, due to a potentially higher hemorrhagic risk of aneurysm rupture. Patients, otherwise, eligible for thrombolysis are usually excluded from receiving this emergent treatment, despite its potential benefits. A reevaluation of the strict exclusion criteria for thrombolysis in acute stroke patients should be considered.

Natalizumab treatment is frequently discontinued and replaced by alternative medication in multiple sclerosis (MS) patients having a high risk of progressive multifocal leukoencephalopathy (PML). Case Presentation. We report a PML case that was missed on magnetic resonance imaging (MRI) at the time Natalizumab treatment was discontinued. The patient subsequently developed a PML-immune reconstitution inflammatory syndrome after the initiation of Fingolimod treatment, suggesting that immune reconstitution may occur even during Fingolimod induced lymphopenia. Conclusion. This report highlights the need for strict drug surveillance using MRI of Natalizumab-associated MS patients at the time of drug discontinuation and beyond. This is important with respect to pharmacovigilance purposes not only for Natalizumab, but also for alternative drugs used after Natalizumab discontinuation. J. Killestein, A. Vennegoor, A. E.

Menkes Disease Presenting with Epilepsia Partialis Continua Sun, 23 Nov 2014 07:59:53 +0000 http://www.hindawi.com/journals/crinm/2014/525784/ Aim. We aim to describe a female patient with Menkes disease who presented with epilepsia partialis continua. Case Presentation. Seventeen-months-old Saudi infant was presented with repetitive seizures and was diagnosed to have epilepsia partialis continua. Discussion. Menkes disease (OMIM: 309400) is considered a rare, X-linked recessive neurodegenerative disorder resulting from a mutation in the gene coding for the copper transporting ATPase (ATP7A). Affected individuals usually present with kinky hair, skeletal changes, prolonged jaundice, hypothermia, developmental regression, decreased tone, spasticity, weakness, and therapy resistant seizures. Conclusion. Raising awareness of abnormal presentation of this rare disease may help in the control of seizures through subcutaneous copper supplementation.

Primary Neuroendocrine Tumor in Brain Thu, 20 Nov 2014 11:53:29 +0000 http://www.hindawi.com/journals/crinm/2014/295253/ The incidence of brain metastases for neuroendocrine tumor (NET) is reportedly 1.5~5%, and the origin is usually pulmonary. A 77-year-old man presented to our hospital with headache and disturbance of specific skilled motor activities. Computed tomography (CT) showed a massive neoplastic lesion originating in the left temporal and parietal lobes that caused a mass edematous effect. Grossly, total resection of the tumor was achieved. Histological examination revealed much nuclear atypia and mitotic figures. Staining for CD56, chromogranin A, and synaptophysin was positive, indicating NET. The MIB-1 index was 37%. Histopathologically, the tumor was diagnosed as NET. After surgery, gastroscopy and colonoscopy were performed, but the origin was not seen. After discharge, CT and FDG-PET (fluoro-2-deoxy-d-glucose positron emission tomography) were performed every 3 months. Two years later we have not determined the origin of the tumor. It is possible that the brain is the primary site of this NET. To our knowledge, this is the first reported case of this phenomenon.

Unpredicted Sudden Death due to Recurrent Infratentorial Hemangiopericytoma Presenting as Massive Intratumoral Hemorrhage: A Case Report and Review of the Literature Sun, 16 Nov 2014 07:35:44 +0000 http://www.hindawi.com/journals/crinm/2014/230681/ Unpredicted sudden death arising from hemangiopericytoma with massive intracranial hemorrhage is quite rare. We encountered a patient with recurrent infratentorial hemangiopericytoma presenting as life-threatening massive intracerebral hemorrhage. A 43-year-old man who had undergone craniotomy for total resection of an infratentorial hemangiopericytoma 17 months earlier presented with morning headache and generalized convulsions. Computed tomography revealed a massive hematoma in the right infratentorial region causing tonsillar herniation and emergency surgery was performed to evacuate the hematoma. Histological findings revealed hemangiopericytoma with hemorrhage. Neurological status remained unimproved and brain death was confirmed postoperatively. Hemangiopericytoma presenting as massive hemorrhage is quite rare. Since the risk of life-threatening massive hemorrhage should be considered, careful postoperative long-term follow-up is very important to identify tumor recurrences, particularly in the posterior cranial fossa, even if the tumor is completely removed.

Myeloid Sarcoma: A Rare Case of an Orbital Mass Mimicking Orbital Pseudotumor Requiring Neurosurgical Intervention Sun, 16 Nov 2014 00:00:00 +0000 http://www.hindawi.com/journals/crinm/2014/395196/ Objective. A rare case of myeloid sarcoma (MS), previously referred to as granulocytic sarcoma or chloroma, is presented. Representing a unique form of acute myeloid leukemia (AML), MS may rarely occur in adults. Even rarer, MS may occur as the initial presentation of AML. Methods. We report a singular and illustrative case of an orbital pseudotumor mimicking mass in a 65-year-old male as the initial presentation of AML. Results. Neurosurgical intervention was required to establish the definitive diagnosis via right modified orbitofrontozygomatic craniotomy as well as to decompress the optic canal, superior orbital fissure, and orbit. Conclusion. Postoperatively, he reported decreased pain and improvement of his vision. Further examination revealed decreased proptosis and improved extraocular mobility. Pathological findings demonstrated MS. We review the literature and discuss the neurosurgical relevance of MS as the initial presentation of AML. Christopher Payne, William C.

Major Cognitive Changes and Micrographia following Globus Pallidus Infarct Wed, 12 Nov 2014 12:04:07 +0000 http://www.hindawi.com/journals/crinm/2014/252486/ Importance. Globus pallidus (GP) lesions are well known to cause motor deficits but are less commonly—and perhaps not conclusively—associated with cognitive problems. Observations. We present a 45-year-old male with no significant neurological or psychological problems who after suffering a GP infarct was subsequently found to have substantial cognitive problems and micrographia. Formal neuropsychological testing was not possible due to lack of patient follow-up. Conclusions and Relevance. Despite the conflicting literature on the association of GP lesions and cognitive deficits, our patient demonstrated significant neuropsychological changes following his stroke. In addition, evidence of micrographia likely adds to the literature on the localization of this finding. Our case thus suggests that neuropsychological testing may be beneficial after GP strokes.

Osmotic Demyelination Syndrome as the Initial Manifestation of a Hyperosmolar Hyperglycemic State Sun, 09 Nov 2014 06:47:49 +0000 http://www.hindawi.com/journals/crinm/2014/652523/ Osmotic demyelination syndrome (ODS) is a life-threatening demyelinating syndrome. The association of ODS with hyperosmolar hyperglycemic state (HHS) has been seldom reported. The aim of this study was to present and discuss previous cases and the pathophysiological mechanisms involved in ODS secondary to HHS. A 47-year-old man arrived to the emergency room due to generalized tonic-clonic seizures and altered mental status. The patient was lethargic and had a Glasgow coma scale of 11/15, muscle strength was 4/5 in both lower extremities, and deep tendon reflexes were diminished. Glucose was 838 mg/dL; serum sodium and venous blood gas analyses were normal. Urinary and plasma ketones were negative. Brain magnetic resonance revealed increased signal intensity on T2-weighted FLAIR images with restricted diffusion on the medulla and central pons. Supportive therapy was started and during the next 3 weeks the patient progressively regained consciousness and muscle strength and was able to feed himself. At 6-month follow-up, the patient was asymptomatic and MRI showed no residual damage. In conclusion, the association of ODS with HHS is extremely rare. The exact mechanism by which HHS produces ODS still needs to be elucidated, but we favor a rapid hypertonic insult as the most plausible mechanism. Karla Victoria Rodríguez-Velver, Analy J.

Stroke after Initiating IV Penicillin for Neurosyphilis: A Possible Jarisch-Herxheimer Reaction Wed, 05 Nov 2014 09:30:52 +0000 http://www.hindawi.com/journals/crinm/2014/548179/ Introduction. Syphilis incidence has increased in the US in the last decade. Jarisch-Herxheimer reaction (JHR) is a well-documented adverse effect of penicillin treatment in syphilis. Stroke has not been reported as part of its phenomenology. Case Report. A 57-year-old man presented with worsening memory. His minimental status examination score was 14/30. Serum RPR test was positive and VDRL test in the CSF was reactive. Within six hours of first dose of IV crystalline penicillin G, he was found to have hemineglect and difficulty moving the left leg. MRI of the brain showed multiple acute ischemic strokes. Immediate MRA ruled out vascular occlusion. Penicillin treatment was stopped. Four hours later, he was found to be febrile and had two episodes of generalized tonic-clonic seizures. Conclusions. We report a case of confirmed neurosyphilis with no known modifiable stroke risk factors, who developed acute ischemic stroke and other constitutional symptoms consistent with JHR after IV penicillin. This is the first reported case in literature where an acute ischemic stroke can be attributed to Jarisch-Herxheimer reaction. Given an increase in incidence of syphilis in recent years, our case underlies the importance of keeping in mind potential catastrophic drug adverse reactions in neurosyphilis patients.

Anton’s Syndrome due to Bilateral Ischemic Occipital Lobe Strokes Mon, 03 Nov 2014 07:16:50 +0000 http://www.hindawi.com/journals/crinm/2014/474952/ We present a case of a patient with Anton’s syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton’s syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

Unique Presentation of Akinetic Mutism and Coexisting Thyroid Storm Relating to Stroke Tue, 28 Oct 2014 13:35:19 +0000 http://www.hindawi.com/journals/crinm/2014/320565/ Akinetic mutism is described in various clinical presentations but typically is defined as a state wherein the patient appears awake but does not move or speak. It can be divided into two different subtypes; the most common subtypes depend on the lesion location, mesencephalic-diencephalic region, also called apathetic akinetic mutism (somnolent mutism), and those involving the anterior cingulate gyrus and adjacent frontal lobes called hyperpathic akinetic mutism. The pathway of akinetic mutism is believed to originate from circuits that link the frontal and subcortical structures. This case reports a 48-year-old African American female with bilateral anterior cerebral artery stroke and akinetic mutism with coexisting thyroid storm. This patient with bilateral anterior cerebral artery infarcts presented with characteristics that are typical for akinetic mutism such as having intact eye movements but an inability to respond to auditory or visual commands. With the incidence of bilateral anterior cerebral artery (ACA) ischemic stroke being rare and the incidence of akinetic mutism secondary to ischemic stroke even rarer, we suspect that this patient potentially had a unilateral occlusion of anomalous anterior cerebral vasculature.

New Onset Refractory Status Epilepticus in a Young Man with H1N1 Infection Tue, 14 Oct 2014 11:39:07 +0000 http://www.hindawi.com/journals/crinm/2014/585428/ Objective. To report a case of refractory status epilepticus (SE) as an unusual early manifestation of H1N1 influenza infection. Introduction. H1N1 neurological complications have been reported and consist mainly of seizures or encephalopathy occurring in children. However, we only found a single report of an adult developing complex partial SE with H1N1 infection. Case Report. A 21-year-old previously healthy man was brought to the emergency room (ER) after a witnessed generalized tonic clonic seizure (GTCS). He was fully alert and afebrile upon ER arrival, but a second GTCS prompted treatment with Lorazepam and Fosphenytoin. The initial EEG showed diffuse slowing, but a repeat one requested as the patient failed to regain consciousness revealed recurrent focal seizures of independent bihemispheric origin, fulfilling the criteria for nonconvulsive SE. Chest X-ray, followed by chest CT scan, showed a left upper lobe consolidation. H1N1 infection was confirmed with PCR on bronchoalveolar lavage material. Despite aggressive treatment with Midazolam, Propofol, and multiple high dose antiepileptic drugs, the electrographic seizures recurred at every attempt to reduce the intravenous sedative drugs. The patient died two weeks after his initial presentation. Conclusion. H1N1 should be added to the list of rare causes of refractory SE, regardless of the patient’s age.

Clinical and Genetic Characteristics of Mexican Patients with Juvenile Presentation of Niemann-Pick Type C Disease Thu, 02 Oct 2014 10:43:47 +0000 http://www.hindawi.com/journals/crinm/2014/785890/ Niemann-Pick type C disease (NPC) is a rare lysosomal disease with a protean presentation, ranging from a fatal neonatal course with visceromegaly to an adult presentation with only neurological or psychiatric symptomatology. In this report we describe the genetic and clinical characteristics of 3 Mexican patients from different families with juvenile presentation of NPC. Clinical examination, imaging of central nervous and gastrointestinal system, and EEG were performed. Genetic studies include sequencing and deletion/duplication analysis of NPC1 and NPC2 genes. All patients presented with cognitive impairment, ataxia, and supranuclear vertical gaze palsy; one case had gelastic cataplexy. Also they developed epilepsy and cortical atrophy and two patients had thinning of corpus callosum. The 3 patients were compound heterozygotes for NPC1 sequence variants, including 5 missense and 1 nonsense mutations: p.P1007A and p.F1087L in Case 1; p.Q921P and p.G992R in Case 2; and p.R348* and p.V1165M in case 3. Mexican patients with juvenile NPC presented with a variable clinical phenotype and compound heterozygosity. This suggests a relative high frequency of mutation carriers as it is reported for European population. Consequently, clinicians should consider NPC as a diagnosis possibility in any adolescent or young adult patient with juvenile dementia and/or ataxia, even in absence of gelastic cataplexy and supranuclear vertical gaze palsy.

From Mild Ataxia to Huntington Disease Phenocopy: The Multiple Faces of Spinocerebellar Ataxia 17 Thu, 02 Oct 2014 10:03:12 +0000 http://www.hindawi.com/journals/crinm/2014/643289/ Introduction. Spinocerebellar ataxia 17 (SCA 17) is a rare autosomal dominant cerebellar ataxia (ADCA) caused by a CAG/CAA expansion in the TBP gene, reported from a limited number of countries. It is a very heterogeneous ADCA characterized by ataxia, cognitive decline, psychiatric symptoms, and involuntary movements, with some patients presenting with Huntington disease (HD) phenocopies. The SCA 17 expansion is stable during parent-child transmission and intrafamilial phenotypic homogeneity has been reported. However, significant phenotypic variability within families has also been observed. Report of the Family. We presently report a Greek family with a pathological expansion of 54 repeats at the SCA 17 locus that displayed remarkable phenotypic variability. Among 3 affected members, one presented with HD phenocopy; one with progressive ataxia, dementia, chorea, dystonia, and seizures, and one with mild slowly progressive ataxia with minor cognitive and affective symptoms. Conclusions. This is the first family with SCA 17 identified in Greece and highlights the multiple faces of this rare disorder, even within the same family. Georgios Koutsis, Marios Panas, George P.

Delayed Cerebral Radiation Necrosis after Neutron Beam Radiation of a Parotid Adenocarcinoma: A Case Report and Review of the Literature Tue, 30 Sep 2014 08:09:48 +0000 http://www.hindawi.com/journals/crinm/2014/717984/ Cerebral radiation necrosis (CRN) is a well described possible complication of radiation for treatment of intracranial pathology. However, CRN as sequelae of radiation to extracranial sites is rare. Neutron beam radiation is a highly potent form of radiotherapy that may be used to treat malignant tumors of the salivary glands. This report describes a patient who underwent neutron beam radiation for a parotid adenocarcinoma and who developed biopsy-confirmed temporal lobe radiation necrosis thirty months later. This represents the longest time interval described to date, from initial neutron radiation for extracranial pathology to development of CRN. Two other detailed case studies exist in the literature and are described in this report. These reports as well as our patient’s case are reviewed, and additional recommendations are made to minimize the development of CRN after extracranial neutron beam radiation. Physicians should include the possible diagnosis of CRN in any patient with new neurologic signs or symptoms and a history of head and neck radiation that included planned fields extending to the base of the skull. Counseling of patients prior to neutron beam radiation should include potential neurologic complications associated with CRN and risks of treatment for CRN including neurosurgical intervention.

Successful Management of Refractory Headache and Facial Pain due to Cavernous Sinus Meningioma with Sphenopalatine Ganglion Radiofrequency Mon, 29 Sep 2014 09:10:19 +0000 http://www.hindawi.com/journals/crinm/2014/923516/ Headaches and facial pain can be extremely difficult to manage for the patient and the clinician. In the medical literature, it has been suggested that the autonomic reflex plays an important role in the pathophysiology of facial neuralgia. The sphenopalatine ganglion is the largest parasympathetic ganglion outside the cranium. It is an easy accessible target for pain management. The application of radiofrequency nerve ablation was described in the medical literature. In this case report, we describe a 54-year-old female. She was diagnosed with a cavernous sinus meningioma. She underwent surgical resection and gamma knife radiosurgery. She was suffering from an intractable hemifacial pain for many years. Her pain started shortly after surgery and continued throughout many years. Sphenopalatine ganglion block in multiple occasions was able to provide temporary relief. The patient’s intractable hemicranial headaches and hemifacial pain responded to the sphenopalatine ganglion radiofrequency nerve ablation. The pain response remained unchanged for 12 months after procedure. This case report increased our current knowledge about the sphenopalatine ganglion role in the headache and facial intractable pain management. The failure of available antalgic medications to adequately control pain in similar patients underscores the need to develop an algorithm for therapies.

Intraoperative Visualization of Bilateral Thrombosis in the Posterior Inferior Cerebellar Artery Apparent in the Telovelomedullary Segment Sun, 28 Sep 2014 11:19:20 +0000 http://www.hindawi.com/journals/crinm/2014/247652/ Unilateral posterior inferior cerebellar artery (PICA) thrombosis is frequent. However, bilateral PICA thrombosis is rare. Herein we report about an intraoperative visualization of a bilateral thrombosis of the telovelomedullary segment of the PICA. A 74-year-old woman was admitted to our department on day two of a bilateral PICA thrombosis with developing cerebellar infarction. Her Glasgow Coma Scale score dropped from 15 to 13, and cranial computed tomography revealed compression of the fourth ventricle with consecutive occlusive hydrocephalus. After the insertion of an external ventricular drainage, the patient underwent urgent suboccipital decompressive craniectomy with removal of infarcted cerebellar tonsils, which allowed the bilateral visualization of the thrombosed telovelomedullary segments. The surgical access may offer surgical therapeutic options in a hyperacute occlusion, such as thromb-/embolectomy or bypass procedures.

Anesthesia Dolorosa of Trigeminal Nerve, a Rare Complication of Acoustic Neuroma Surgery Thu, 25 Sep 2014 13:09:18 +0000 http://www.hindawi.com/journals/crinm/2014/496794/ Anesthesia dolorosa is an uncommon deafferentation pain that can occur after traumatic or surgical injury to the trigeminal nerve. This creates spontaneous pain signals without nociceptive stimuli. Compression of the trigeminal nerve due to acoustic neuromas or other structures near the cerebellopontine angle (CPA) can cause trigeminal neuralgia, but the occurrence of anesthesia dolorosa subsequent to acoustic tumor removal has not been described in the medical literature. We report two cases of acoustic neuroma surgery presented with anesthesia dolorosa along the trigeminal nerve distribution. The patients’ pain was managed with multidisciplinary approaches with moderate success. Foad Elahi and Kwo Wei David Ho Copyright © 2014 Foad Elahi and Kwo Wei David Ho. All rights reserved. Breakfast Time Blackouts Thu, 18 Sep 2014 16:11:32 +0000 http://www.hindawi.com/journals/crinm/2014/568983/ We present the case of a 16-year-old girl who suffered from repeated episodes of collapse and loss of consciousness which could be provoked by undertaking a stretching manoeuvre comprising a combined breath hold and neck torsion. A review of the literature is provided on other cases of so-called “stretch syncope” which appears to be a rare form of reflex syncope affecting patients in adolescence. Andrew W.

Acute Psychosis Associated with Subcortical Stroke: Comparison between Basal Ganglia and Mid-Brain Lesions Thu, 18 Sep 2014 00:00:00 +0000 http://www.hindawi.com/journals/crinm/2014/428425/ Acute onset of psychosis in an older or elderly individual without history of previous psychiatric disorders should prompt a thorough workup for neurologic causes of psychiatric symptoms. This report compares and contrasts clinical features of new onset of psychotic symptoms between two patients, one with an acute basal ganglia hemorrhagic stroke and another with an acute mid-brain ischemic stroke. Delusions and hallucinations due to basal ganglia lesions are theorized to develop as a result of frontal lobe dysfunction causing impairment of reality checking pathways in the brain, while visual hallucinations due to mid-brain lesions are theorized to develop due to dysregulation of inhibitory control of the ponto-geniculate-occipital system. Psychotic symptoms occurring due to stroke demonstrate varied clinical characteristics that depend on the location of the stroke within the brain. Treatment with antipsychotic medications may provide symptomatic relief. Aaron McMurtray, Ben Tseng, Natalie Diaz, Julia Chung, Bijal Mehta, and Erin Saito Copyright © 2014 Aaron McMurtray et al.

Congenital Insensitivity to Pain: A Case Report and Review of the Literature Thu, 18 Sep 2014 00:00:00 +0000 http://www.hindawi.com/journals/crinm/2014/141953/ Congenital insensitivity to pain (CIP) is a rare autosomal recessive genetic disease caused by mutations in the SCN9A gene. We report a patient with the clinical features consistent with CIP in whom we detected a novel homozygous G2755T mutation in exon 15 of this gene. Routine electrophysiological studies are typically normal in patients with CIP. In our patient, these studies were abnormal and could represent the consequences of secondary complications of cervical and lumbosacral spine disease and associated severe Charcot’s joints.

Neurenteric Cyst of the Area Postrema Tue, 16 Sep 2014 06:23:32 +0000 http://www.hindawi.com/journals/crinm/2014/718415/ Neurenteric cysts are CNS lesions most frequently occurring in the spinal cord. Intracranial neurenteric cysts are rarer, typically presenting with headache, mass effect, or location-specific symptoms. The area postrema is known as the emetic center of the brain; lesions can cause nausea and vomiting. Our case, featuring a neurenteric cyst of the area postrema, illustrates the importance of considering a neurological etiology for nonspecific symptoms that otherwise elude explanation. Our patient presented with acute decompensated hydrocephalus upon exploratory abdominal laparoscopy for unresolving abdominal pain. The patient had an eight-month history of unexplained intermittent nausea, vomiting, and abdominal pain. These bouts increased in frequency during the weeks before acute presentation, prompting exploratory abdominal laparoscopy. The acute decompensation was managed by ventriculostomy, and cranial MRI revealed a cystic mass by the floor of the fourth ventricle. After the patient stabilized and returned to neurological baseline, suboccipital craniectomy and resection were performed. The mass was histologically identified as a neurenteric cyst. The patient was free from neurological complaints at one-year follow-up, indicating that the successful resection of the area postrema-associated neurenteric cyst resolved her previous symptoms. Thus, some intracranial lesions can masquerade as nonspecific symptoms, presenting a challenge to accurate diagnosis. Claire M. Miller, Bonnie H.

Optic Nerve Injury in a Patient with Chronic Allergic Conjunctivitis Mon, 15 Sep 2014 08:18:11 +0000 http://www.hindawi.com/journals/crinm/2014/928486/ Manipulation of the optic nerve can lead to irreversible vision changes. We present a patient with a past medical history of skin allergy and allergic conjunctivitis (AC) who presented with insidious unexplained unilateral vision loss. Physical exam revealed significant blepharospasm, mild lid edema, bulbar conjunctival hyperemia, afferent pupillary defect, and slight papillary hypertrophy. Slit lamp examination demonstrated superior and inferior conjunctival scarring as well as superior corneal scarring but no signs of external trauma or neurological damage were noted. Conjunctival cultures and cytologic evaluation demonstrated significant eosinophilic infiltration. Subsequent ophthalmoscopic examination revealed optic nerve atrophy. Upon further questioning, the patient admitted to vigorous itching of the affected eye for many months. Given the presenting symptoms, history, and negative ophthalmological workup, it was determined that the optic nerve atrophy was likely secondary to digital pressure from vigorous itching. Although AC can be a significant source of decreased vision via corneal ulceration, no reported cases have ever described AC-induced vision loss of this degree from vigorous itching and chronic pressure leading to optic nerve damage. Despite being self-limiting in nature, allergic conjunctivitis should be properly managed as extreme cases can result in mechanical compression of the optic nerve and compromise vision.

Video Self-Modeling Is an Effective Intervention for an Adult with Autism Wed, 03 Sep 2014 11:04:26 +0000 http://www.hindawi.com/journals/crinm/2014/425897/ With the increases in size and strength that come with adulthood, challenging behaviours among those with autism spectrum disorders (ASD) can become critical. Few studies have explored behavioural interventions in adults with ASD, though recent studies have shown video self-modeling (VSM) to be effective in children with ASD. VSM involves an individual watching videos of himself demonstrating prosocial behaviours, while those behaviours are pointed out and encouraged. In the current study, VSM was used to encourage prosocial behaviours and to reduce problematic behaviour displayed by an adult with ASD. Results reveal a decrease in the tendency to invade others’ personal space and make inappropriate loud noises. VSM may be an effective intervention and improve the lives of adults with ASD.

Clinical Pathway in the Treatment of Nocardial Brain Abscesses following Systemic Infections Thu, 28 Aug 2014 11:22:55 +0000 http://www.hindawi.com/journals/crinm/2014/584934/ Nocardial infections are commonly encountered in patients with immunocompromised states. Cerebral nocardiosis is an uncommon clinical entity, representing only 2% of all cerebral abscesses. It has a higher mortality rate, especially for multiple cerebral lesions in immunocompromised hosts following systemic infections. However, an optimal treatment policy to deal with these immunocompromised patients in Asia is still lacking. We retrospectively reviewed the subjects with nocardial brain abscesses from 2001 to 2011 at our medical center. All of them had multiple brain abscesses, underlying with immunocompromised state following systemic infections. All cases were under steroid control due to their comorbidities for more than six months. The comorbidities and misdiagnosis often lead to poor prognosis. The change in the environments of the microorganisms caused by immunosuppressive agents and multiple antibiotic uses may play an important role in this critical disorder. Aggressive craniotomy should be performed in time to avoid grievous neurological outcomes. Our conclusion is that early diagnosis and appropriate antibiotic uses should be implemented promptly, and aggressive craniotomy should be performed for nocardial brain abscesses in subjects with systemic infections under an immunocompromised status.

Cerebral Air Embolism from Angioinvasive Cavitary Aspergillosis Thu, 14 Aug 2014 11:33:36 +0000 http://www.hindawi.com/journals/crinm/2014/406106/ Background. Nontraumatic cerebral air embolism cases are rare. We report a case of an air embolism resulting in cerebral infarction related to angioinvasive cavitary aspergillosis. To our knowledge, there have been no previous reports associating these two conditions together. Case Presentation. A 32-year-old female was admitted for treatment of acute lymphoblastic leukemia (ALL). Her hospital course was complicated by pulmonary aspergillosis. On hospital day 55, she acutely developed severe global aphasia with right hemiplegia. A CT and CT-angiogram of her head and neck were obtained demonstrating intravascular air emboli within the left middle cerebral artery (MCA) branches. She was emergently taken for hyperbaric oxygen therapy (HBOT). Evaluation for origin of the air embolus revealed an air focus along the left lower pulmonary vein. Over the course of 48 hours, her symptoms significantly improved. Conclusion. This unique case details an immunocompromised patient with pulmonary aspergillosis cavitary lesions that invaded into a pulmonary vein and caused a cerebral air embolism. With cerebral air embolisms, the acute treatment option differs from the typical ischemic stroke pathway and the provider should consider emergent HBOT. This case highlights the importance of considering atypical causes of acute ischemic stroke. Chen Lin, George A. Barrio, Lynne M. Hurwitz, and Peter G. Kranz Copyright © 2014 Chen Lin et al.

Multiple Sclerosis Presents with Psychotic Symptoms and Coexists with Hypertrophic Cardiomyopathy Wed, 13 Aug 2014 09:30:29 +0000 http://www.hindawi.com/journals/crinm/2014/383108/ Multiple sclerosis (MS) is a demyelinating disease of the central nervous system. Psychiatric symptoms are not infrequent during MS, yet onset of MS with psychosis is rarely encountered. A 27-year-old Caucasian male was admitted due to numbness in his right arm and difficulty in walking. His clinical and laboratorial exams lead to the MS diagnosis. Nine months earlier, he also developed psychotic disorder, not otherwise specified (PD-NOS). His sudden onset of PD-NOS, his rapid and complete response to antipsychotics, and a relatively short interval between psychiatric and neurological signs indicate a high likelihood that PD-NOS was a manifestation of underlying MS. He also suffers from hypertrophic obstructive cardiomyopathy (HOCM). The patient’s neurological complaints were recovered with methylprednisolone (1 g/day, i.v.) given for five days. Glatiramer acetate (1 × 1 tb.s.c.) was prescribed for consolidation and, after nine months of his admission, the patient fully recovered from neurological and psychiatric complaints. Interestingly, very recent studies indicate specific alpha-actinin antibodies in MS and alpha-actinin mutations cause HOCM. Thus, concurrence of MS with HOCM can be even a new syndrome, if further genetic studies prove.

Multiple Sclerosis and Oligodendroglioma: An Exceptional Association Thu, 07 Aug 2014 11:06:26 +0000 http://www.hindawi.com/journals/crinm/2014/546817/ The cooccurrence of multiple sclerosis (MS) and oligodendroglioma is very rare. We present a 43-year-old male patient with the diagnosis of MS lasting for 14 years who developed seizures and right hemiparesis; cerebral MRI revealed an already known extensive lesion, previously misdiagnosed as tumefactive demyelinating lesion. Cerebral biopsy leads to oligodendroglioma diagnosis, successfully treated with radiotherapy. The diagnosis of a brain tumor in a MS patient is challenging. The atypical clinical and radiological features are the key for accurate diagnosis. In such cases, a brain tumor has to be kept in mind no matter how rare this association is.

Minimally Invasive Subcortical Parafascicular Transsulcal Access for Clot Evacuation (Mi SPACE) for Intracerebral Hemorrhage Wed, 06 Aug 2014 07:17:46 +0000 http://www.hindawi.com/journals/crinm/2014/102307/ Background. Spontaneous intracerebral hemorrhage (ICH) is common and causes significant mortality and morbidity. To date, optimal medical and surgical intervention remains uncertain. A lack of definitive benefit for operative management may be attributable to adverse surgical effect, collateral tissue injury. This is particularly relevant for ICH in dominant, eloquent cortex. Minimally invasive surgery (MIS) offers the potential advantage of reduced collateral damage. MIS utilizing a parafascicular approach has demonstrated such benefit for intracranial tumor resection. Methods. We present a case of dominant hemisphere spontaneous ICH evacuated via the minimally invasive subcortical parafascicular transsulcal access clot evacuation (Mi SPACE) model. We use this report to introduce Mi SPACE and to examine the application of this novel MIS paradigm. Case Presentation. The featured patient presented with a left temporal ICH and severe global aphasia. The hematoma was evacuated via the Mi SPACE approach. Postoperative reassessments showed significant improvement. At two months, bedside language testing was normal. MRI tractography confirmed limited collateral injury. Conclusions. This case illustrates successful application of the Mi SPACE model to ICH in dominant, eloquent cortex and subcortical regions. MRI tractography illustrates collateral tissue preservation. Safety and feasibility studies are required to further assess this promising new therapeutic paradigm.
