Colon Adenoma Implicating Myasthenia Gravis: A Case Report of a Patient with Postcolectomy Complications Wed, 17 Aug 2016 14:01:51 +0000 We report the case of a 63-year-old patient with myasthenia gravis (MG) due to acetylcholine receptor antibodies (AChR) who underwent colectomy due to colon adenoma and developed myasthenic crisis and anastomosis leakage after surgery. The patient underwent two plasma exchanges, 4 and 6 days preoperatively, and received intravenous prednisolone and immunoglobulin infusion due to the crisis, which included primarily bulbar symptoms. The patient developed on the 10th postoperative day bowel obstruction symptoms and anastomosis leakage which required surgical repair and ileostomy. Bowel obstruction occurred in a patient with AChR related myasthenia after plasma exchange and during immunosuppression although it is more commonly reported in patients with thymoma related myasthenia.

Adult Primary Spinal Epidural Extraosseous Ewing’s Sarcoma: A Case Report and Review of the Literature Wed, 17 Aug 2016 07:59:29 +0000 Background. Extraosseous Ewing’s sarcoma in the spinal epidural space is a rare malignancy, especially in adults. Case Presentation. A 40-year-old male presented with back pain and urinary hesitancy. MRI revealed a thoracic extradural mass with no osseous involvement. He underwent surgery for gross total resection of the mass, which was diagnosed as Ewing’s sarcoma. He was subsequently treated with chemoradiotherapy. He remains disease-free 1 year after surgery. Review of the literature indicated only 45 previously reported cases of spinal epidural extraosseous Ewing’s sarcoma in adults. Conclusions. Extraosseous Ewing’s sarcoma in the spinal epidural space is a rare clinical entity that should be included in the differential for spinal epidural masses. Its treatment is multidisciplinary but frequently requires surgical intervention due to compressive neurologic symptoms. Gross total resection appears to correlate with improved outcomes.

With increasing reliance on electronic communication, incoherent texting or “dystextia,” which is a subset of aphasia that is reflected in text messages, can be a useful tool for symptom recognition and analysis. It can be a red flag for the family and therefore can help in early identification of an acute neurological deficit. It is also useful for providers to reliably analyze the deficit as well as establish a timeline of evolution of symptoms. There have been case reports where dystextia has been the presenting feature of stroke or complicated migraine and in one case of meningioma. We present the case of a teenage patient that in our knowledge is the youngest reported case of dystextia, whose aphasia recorded in a text message assisted with stroke localization. This also adds to the literature of dystextia which so far has only seven other cases reported. Arpita Lakhotia, Alok Sachdeva, Supriya Mahajan, and Nancy Bass Copyright © 2016 Arpita Lakhotia et al.

Effect of Spinal Cord Stimulation on Gait in a Patient with Thalamic Pain Sun, 07 Aug 2016 13:34:46 +0000 Thalamic pain is a central neuropathic pain disorder which occurs after stroke. Its severe chronic pain is often intractable to pharmacotherapies and affects the patients’ activities of daily living (ADL) and quality of life (QOL). Recently, spinal cord stimulation (SCS) has been reported to be effective in relieving the pain of thalamic pain; however, the effect of SCS on gait performance in patients is unknown. Therefore, we evaluated the gait performance before and after SCS in a case with thalamic pain. A 73-year-old male with thalamic pain participated in this study. We evaluated the gait of the patient two times: before SCS insertion and after 6 days of SCS. At the second evaluation, we measured the gait in three conditions: stimulation off, comfortable stimulation, and strong stimulation. SCS succeeded in improving the pain from 7 to 2 on an 11-point numerical rating scale. Step frequency and the velocity of gait tended to increase between pre- and poststimulation periods. There were no apparent differences in gait among the three stimulation conditions (off, comfortable, and strong) at the poststimulation period. SCS may be effective on gait in patients with thalamic pain.

Progressive Multifocal Leukoencephalopathy in a HIV Negative, Immunocompetent Patient Wed, 27 Jul 2016 12:21:47 +0000 Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating disease most common in immunodeficient patients. It occurs due to reactivation of the John Cunningham Virus (JCV) and carries a poor prognosis, with a median life expectancy of 6 months. We report a case of a 66-year-old man with a history of HCV related cirrhosis (HCV) and hepatocellular carcinoma (HCC) who was found to have PML in the setting of a negative viral load in the CSF and a CD4+ >200. He initially presented with two weeks of mild confusion and word-finding difficulty concerning for hepatic encephalopathy. An MRI was notable for extensive T2/FLAIR hyperintensity signal in the left temporal lobe. Brain biopsy was positive for JCV. PML is rare in immunocompetent individuals, especially in the setting of a negative viral load. It is possible, however, that transient states of immunosuppression may have been responsible in this case. Although viral load was reported as negative, virus may still have been detected but was below the quantifiable threshold. It is important for clinicians to note that a negative result does not necessarily exclude the possibility of PML, and care should be taken to review lab values on viral load in closer detail. T.

Unusual Late Onset of Parenchymal Neuro-Behçet Disease Tue, 26 Jul 2016 17:39:41 +0000 Neuro-Behçet disease (NBD) is a multisystem inflammatory disorder characterized by oral lesions, genital lesions, uveitis, and neurological deficits. If left untreated, it may lead to worsening neurological function and can be fatal. Here we present a case of a 52-year-old woman who was diagnosed with Behçet disease (BD) as a teenager and had a relatively mild disease course. Decades later after her initial DB diagnosis, she presented to our hospital with a chief complaint of headache. She did not have focal neurological deficits or any active mucosal lesions. Upon further investigation, the patient was found to have multiple inflammatory changes on neuroimaging and abnormal cerebrospinal fluid (CSF), consistent with the diagnosis of NBD. She was treated with intravenous corticosteroid therapy and her symptoms resolved. Although our patient presented with minimal symptoms decades after her initial diagnosis, any neurological complaint warranted a thorough investigation for a proper diagnosis and treatment given the multisystem involvement of BD.

Advanced Genetic Testing Comes to the Pain Clinic to Make a Diagnosis of Paroxysmal Extreme Pain Disorder Thu, 21 Jul 2016 12:14:22 +0000 Objective. To describe the use of an advanced genetic testing technique, whole exome sequencing, to diagnose a patient and their family with a SCN9A channelopathy. Setting. Academic tertiary care center. Design. Case report. Case Report. A 61-year-old female with a history of acute facial pain, chronic pain, fibromyalgia, and constipation was found to have a gain of function SCN9A mutation by whole exome sequencing. This mutation resulted in an SCN9A channelopathy that is most consistent with a diagnosis of paroxysmal extreme pain disorder. In addition to the patient being diagnosed, four siblings have a clinical diagnosis of SCN9A channelopathy as they have consistent symptoms and a sister with a known mutation. For treatment, gabapentin was ineffective and carbamazepine was not tolerated. Nontraditional therapies improved symptoms and constipation resolved with pelvic floor retraining with biofeedback. Conclusion. Patients with a personal and family history of chronic pain may benefit from a referral to Medical Genetics. Pelvic floor retraining with biofeedback should be considered for patients with a SCN9A channelopathy and constipation. Ashley Cannon, Svetlana Kurklinsky, Kimberly J. Guthrie, and Douglas L.

Diagnostic Challenges of Cryptococcus neoformans in an Immunocompetent Individual Masquerading as Chronic Hydrocephalus Wed, 20 Jul 2016 15:05:28 +0000 Cryptococcus neoformans can cause disseminated meningoencephalitis and evade immunosurveillance with expression of a major virulence factor, the polysaccharide capsule. Direct diagnostic assays often rely on the presence of the cryptococcal glucuronoxylomannan capsular antigen (CrAg) or visualization of the capsule. Strain specific phenotypic traits and environmental conditions influence differences in expression that can thereby compromise detection and timely diagnosis. Immunocompetent hosts may manifest clinical signs and symptoms indolently, often expanding the differential and delaying appropriate treatment and diagnosis. We describe a 63-year-old man who presented with a progressive four-year history of ambulatory dysfunction, headache, and communicating hydrocephalus. Serial lumbar punctures (LPs) revealed elevated protein (153–300 mg/dL), hypoglycorrhachia (19–47 mg/dL), lymphocytic pleocytosis (89–95% lymphocyte, WBC 67–303 mg/dL, and RBC 34–108 mg/dL), and normal opening pressure (13–16 cm H2O). Two different cerebrospinal fluid (CSF) CrAg assays were negative. A large volume CSF fungal culture grew unencapsulated C. neoformans. He was initiated on induction therapy with amphotericin B plus flucytosine and consolidation/maintenance therapy with flucytosine, but he died following discharge due to complications. Elevated levels of CSF Th1 cytokines and decreased IL6 may have affected the virulence and detection of the pathogen. Kedar R. Mahajan, Amity L. Roberts, Mark T.

Horner’s Syndrome due to a Spontaneous Internal Carotid Artery Dissection after Deep Sea Scuba Diving Wed, 20 Jul 2016 13:39:17 +0000 Internal carotid artery dissection (ICAD) is a rare entity that either results from traumatic injury or can be spontaneously preceded or not by a minor trauma such as sporting activities. It represents a major cause of stroke in young patients. The diagnosis should be suspected with the combination of Horner’s syndrome, headache or neck pain, and retinal or cerebral ischaemia. The confirmation is frequently made with a magnetic resonance angiography (MRA). Although anticoagulation with heparin followed by vitamin-K-antagonists is the most common treatment, there is no difference in efficacy of antiplatelet and anticoagulant drugs at preventing stroke and death in patients with symptomatic carotid dissection. We describe a patient with ICAD following deep sea scuba diving, who presented with Horner’s syndrome and neck pain and was successfully treated with anticoagulants.

Carotid Space Mass Proximal to Vagus Nerve Causing Asystole and Syncope Tue, 19 Jul 2016 14:31:34 +0000 Manipulation of vagal nerve rootlets, whether surgical or through mass effect of a neoplasm, can result in asystole and hypotension, accompanied by ST depression and right bundle branch block. There are few case reports of a neoplasm causing these effects, and this case describes a patient with such a mass presenting with syncopal episodes. A 43-year-old man with a past medical history of HIV, bipolar disorder, and epilepsy was admitted to the neurology service for a video electroencephalogram (vEEG) to characterize syncopal episodes that were felt to be epileptic in origin. During the study, he experienced symptoms of his typical aura, which correlated with a transient symptomatic high degree AV block on telemetry, and an absence of epileptic findings on vEEG. Magnetic Resonance Imaging (MRI) of the brain showed a mass in the left posterior carotid space at the skull base. The patient underwent permanent dual chamber MRI-compatible pacemaker placement for his heart block. His syncopal episodes resolved, but presyncopal symptoms persisted. We discuss the presentation and treatment of vagal neoplasms. Julie Leviter and Daniel H. Wiznia Copyright © 2016 Julie Leviter and Daniel H. Wiznia. All rights reserved. Acute Disseminated Encephalomyelitis following Vaccination against Hepatitis B in a Child: A Case Report and Literature Review Tue, 12 Jul 2016 14:08:57 +0000 Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system, which has been associated with several vaccines such as rabies, diphtheria-tetanus-polio, smallpox, measles, mumps, rubella, Japanese B encephalitis, pertussis, influenza, and the Hog vaccine. Here, we presented a case of 12-year-old child who suffered from ADEM three weeks after hepatitis B vaccination. He was admitted to our hospital with symptoms of weakness of limbs, high fever, and alteration of consciousness. Some abnormalities were also found in CSF. Treatment with high-dose corticosteroids and intravenous immunoglobulin had significant effect, with marked improvement of the clinical symptoms and the results of CSF. The findings of MRI also detected some abnormal lesions located in both brain and spinal cord. The clinical features, the findings of CSF and MRI, and therapeutic effect may contribute to such diagnosis of ADEM.

Acute Paraplegia due to Thoracic Hematomyelia Tue, 12 Jul 2016 09:11:28 +0000 Spontaneous intraspinal intramedullary hemorrhage is a rare entity with the acute onset of neurologic symptoms. The etiology of idiopathic spontaneous hematomyelia (ISH) is unknown, and there are few published case reports. Hematomyelia is mostly associated with trauma, but the other nontraumatic etiologies are vascular malformations, tumors, bleeding disorders, syphilis, syrinx, and myelitis. MRI is a good choice for early diagnosis. Hematomyelia usually causes acute spinal cord syndrome due to the compression and destruction of the spinal cord. A high-dose steroid treatment and surgical decompression and evacuation of hematoma are the urgent solution methods. We present idiopathic spontaneous hematomyelia of a previously healthy 80-year-old male with a sudden onset of back pain and paraplegia.

Paradoxical Herniation following Decompressive Craniectomy in the Subacute Setting Thu, 30 Jun 2016 10:27:35 +0000 Decompressive craniectomy is reserved for extreme cases of intracranial hypertension. An uncommon complication known as paradoxical herniation has been documented within weeks to months following surgery. Here we present a unique case within days of surgery. Since standard medical treatment for intracranial hypertension will exacerbate paradoxical herniation, any abrupt neurological changes following decompressive craniectomy should be carefully investigated. Immediate treatment for paradoxical herniation is placement of the patient in the supine position with adequate hydration. Cranioplasty is the ultimate treatment option. Alex P.

Management of a Low-Energy Penetrating Brain Injury Caused by a Nail Sun, 26 Jun 2016 13:28:12 +0000 Low-energy penetrating nail injury to the brain is an extremely rare neurosurgical emergency. The most common cause of nail gun injury is work related accidents; other causes result from accidental firing of a nail gun, suicide attempts by firing nail guns into the brain, and bomb blasts containing pieces of nails. Neurosurgical treatment performed by craniotomy still seems to be the safest one; there are reports of complications such as subdural hematoma and intraparenchymal hemorrhages following the blind removal of foreign bodies leading to suggestions that all penetrating foreign bodies should be removed under direct vision. We report a rarely described neurosurgical approach for removal of a penetrating nail from the brain and skull without evidence of associated hematoma and other brain lesions. V. R. Ferraz, G. B.

Reversible Akinetic Mutism after Aneurysmal Subarachnoid Haemorrhage in the Territory of the Anterior Cerebral Artery without Permanent Ischaemic Damage to Anterior Cingulate Gyri Thu, 23 Jun 2016 11:47:02 +0000 We report on two cases of transient akinetic mutism after massive subarachnoid haemorrhage due to the rupture of an intracranial aneurysm of the anterior cerebral artery (ACA). In the two cases, vasospasm could not be demonstrated by imaging studies throughout the clinical course. Both patients shared common radiological features: a hydrocephalus due to haemorrhagic contamination of the ventricular system and a mass effect of a subpial hematoma on the borders of the corpus callosum. Patients were also investigated using auditory event-related evoked potentials at acute stage. In contrast to previous observations of akinetic mutism, P300 wave could not be recorded. Both patients had good recovery and we hypothesized that this unexpectedly favourable outcome was due to the absence of permanent structural damage to the ACA territory, with only transient dysfunction due to a reversible mass effect on cingulate gyri.

Posterior Reversible Encephalopathy Syndrome with Bilateral Independent Epileptic Foci Precipitated By Guillain-Barrè Syndrome Wed, 15 Jun 2016 11:17:47 +0000 We report the case of a 56-year-old woman who developed status epilepticus (SE) related to independent occipital foci as clinical manifestation of posterior reversible encephalopathy syndrome (PRES) in the background of Guillain-Barrè syndrome (GBS). SE resulted from a series of focal seizures clinically characterized by left- and rightward deviations of the head and consequent oculoclonic movements. Electroencephalography recorded independent seizure activity in both occipital regions with alternate involvement of the two cerebral hemispheres. The epileptic foci corresponded topographically to parenchymal abnormalities of PRES in the occipital lobes. The manifestation of bilateral, independent occipital seizures with alternate deviations of the head and oculoclonic movements, previously not reported in patients with PRES, highlights the acute epileptogenicity of the cerebral lesions in this syndrome. Despite the variable clinical expression of seizures due to occipital damage in PRES, the development of independent seizure activity in both occipital lobes might represent a distinctive epileptic phenomenon of this encephalopathy.

Lesion in Scalp and Skull as the First Manifestation of Hepatocellular Carcinoma Tue, 14 Jun 2016 11:54:57 +0000 Hepatocellular carcinoma (HCC) is the most common primary tumor of the liver and the fifth most common cancer in the world. The lungs, bone, and lymph nodes are frequent sites of metastasis of HCC. The purpose of the present study is show that metastases, although rare, must be among the differential diagnosis of skin lesions and that a diagnostic research based on these findings can be conducted. The authors report a rare case of metastatic hepatocellular injury to the scalp and skull treated by a radical surgical approach. Excision of the lesion in the scalp was performed “en bloc.” The tumor was supplied by the frontal branch of the superficial temporal artery. There are few case reports of metastatic HCC to scalp and skull; treatment of these lesions should be individualized in order to control symptoms, improve quality of life, and promote an increase in survival.

GNE Myopathy in Turkish Sisters with a Novel Homozygous Mutation Thu, 19 May 2016 13:22:19 +0000 Background. Hereditary inclusion body myopathy is caused by biallelic defects in the GNE gene located on chromosome 9p13. It generally affects adults older than 20 years of age. Methods and Results. In this study, we present two Turkish sisters with progressive myopathy and describe a novel mutation in the GNE gene. Both sisters had slightly higher levels of creatine kinase (CK) and muscle weakness. The older sister presented at 38 years of age with an inability to climb steps, weakness, and a steppage gait. Her younger sister was 36 years old and had similar symptoms. The first symptoms of the disorder were seen when the sisters were 30 and 34 years old, respectively. The muscle biopsy showed primary myopathic features and presence of rimmed vacuoles. DNA analysis demonstrated the presence of previously unknown homozygous mutations [c.2152 G>A (p.A718T)] in the GNE genes. Conclusion. Based on our literature survey, we believe that ours is the first confirmed case of primary GNE myopathy with a novel missense mutation in Turkey. These patients illustrate that the muscle biopsy is still an important method for the differential diagnosis of vacuolar myopathies in that the detection of inclusions is required for the definitive diagnosis.

Nonvisualization of the Internal Carotid Artery on Computed Tomography Angiography: Discussion of Two Cases with Review of Literature Thu, 19 May 2016 10:58:09 +0000 Nonvisualization of the internal carotid artery (ICA) on cross-sectional imaging studies can be due to congenital (dysgenesis of the ICA) or acquired (complete occlusion of ICA) causes. We report two cases, one with absent carotid canal on bone window setting of computed tomography (CT) suggestive of congenital cause and the other with normal carotid canal, suggesting acquired cause. Development of aortic arches with six pathways of collateral circulation in brain is also discussed. Sonal Saran, Rengarajan Rajagopal, Pushpinder S.

Recurrent Diplopia in a Pediatric Patient with Bickerstaff Brainstem Encephalitis Tue, 17 May 2016 12:56:17 +0000 Introduction. Acute complete external ophthalmoplegia is a rare finding in clinical practice that is associated with diseases affecting the neuromuscular junction, the oculomotor nerves, or the brainstem. Ophthalmoplegia has been reported with acute ataxia in Miller Fisher syndrome (MFS) and Bickerstaff brainstem encephalitis (BBE). Up to 95% of these cases are associated with anti-GQ1b antibodies. Only a small number of cases of anti-GQ1b negative MFS have been documented in pediatric patients. This is the first case reporting a recurrence of ocular symptoms in an anti-GQ1b antibody negative patient with BBE. Case Presentation. An 8-year-old Caucasian boy presented with complete external ophthalmoplegia without ptosis, cerebellar ataxia, and a disturbance of consciousness. He had recently recovered from a confirmed Campylobacter jejuni infection. On subsequent laboratory testing he was anti-GQ1b antibody negative. He had a recurrence of diplopia at four-week follow-up. Conclusions. This patient’s recurrence of diplopia was treated with a five-week course of oral corticosteroids which did not worsen his condition, and this may be a therapeutic option for similar patients. We will discuss the symptoms and treatment of reported pediatric cases of anti-GQ1b antibody negative cases of MFS and the variation between cases representing a spectrum of illness. Scott A.

Morvan Syndrome Secondary to Thymic Carcinoma in a Patient with Systemic Lupus Erythematosus Tue, 10 May 2016 16:32:11 +0000 Morvan syndrome (MoS) is a rare paraneoplastic autoimmune disorder characterized by peripheral nerve hyperexcitability, autonomic dysfunction, and sleep disorders. Systemic lupus erythmatosus (SLE) cooccurs in 6–10% of patients with thymoma. It may occur before, concurrently with, or after thymoma diagnosis. This paper reports the first case of cooccurrence of SLE, thymic carcinoma, and MoS. The cooccurrence of SLE, thymoma, and MoS delineates the generalized autoimmunity process. Symptoms of both MoS and SLE abated upon tumor resection. Gabrielle Macaron, Elie El Rassy, and Salam Koussa Copyright © 2016 Gabrielle Macaron et al. All rights reserved. Primary Intracranial Synovial Sarcoma Mon, 09 May 2016 11:33:58 +0000 Background. Synovial sarcoma is an aggressive soft tissue sarcoma with uncertain histological origin. The pathology frequently presents as a localized disease, especially near large joints around the knee and thigh. Intracranial disease, which is rare, has been reported as metastasis from synovial sarcoma. We report a case with no obvious primary extracranial pathology, suggesting primary intracranial disease; this has not been reported in the literature. Case Description. A 21-year-old male, with a prior right skull lesion resection for atypical spindle cell neoplasm, presented with headaches, gait instability, left arm weakness, and left homonymous hemianopsia. CT of head demonstrated a right parietal hemorrhagic lesion with mass effect, requiring surgical decompression. Histopathology revealed synovial sarcoma. FISH analysis noted the existence of the t(X;18)(p11.2;q11.2) chromosomal translocation. PET scan did not show other metastatic disease. He underwent stereotactic radiotherapy and adjuvant chemotherapy. At 2-year follow-up, he remained nonfocal without recurrence. Conclusion. We report the first known case of primary intracranial synovial sarcoma. Moreover, we stress that intracranial lesions may have a tendency for hemorrhage, requiring urgent lifesaving decompression.

High-Grade Glioma of the Ventrolateral Medulla in an Adult: Case Presentation and Discussion of Surgical Considerations Sun, 08 May 2016 12:24:23 +0000 Background. High-grade gliomas of the brainstem are rare in adults and are particularly rare in the anterolateral medulla. We describe an illustrative case and discuss the diagnostic and treatment issues associated with a tumor in this location, including differential diagnosis, anatomical considerations for options for surgical management, multimodality treatment, and prognosis. Case Description. A 69-year-old woman presented with a 3-week history of progressive right lower extremity weakness. She underwent an open biopsy via a far lateral approach with partial condylectomy, which revealed a glioblastoma. Concurrent temozolomide and radiation were completed; however, she elected to stop her chemotherapy after 5.5 weeks of treatment. She succumbed to her disease 11 months after diagnosis. Conclusions. Biopsy can be performed relatively safely to provide definitive diagnosis to guide treatment, but long-term prognosis is poor. Angela Spurgeon, Viet Le, Sanjay Konakondla, Douglas C.

Imaging Evidence for Cerebral Hyperperfusion Syndrome after Intravenous Tissue Plasminogen Activator for Acute Ischemic Stroke Tue, 03 May 2016 09:22:01 +0000 Background. Cerebral hyperperfusion syndrome (CHS), a rare complication after cerebral revascularization, is a well-described phenomenon after carotid endarterectomy or carotid artery stenting. However, the imaging evidence of CHS after intravenous tissue plasminogen activator (iv tPA) for acute ischemic stroke (AIS) has not been reported. Case Report. Four patients were determined to have manifestations of CHS with clinical deterioration after treatment with iv tPA, including one patient who developed seizure, one patient who had a deviation of the eyes toward lesion with worsened mental status, and two patients who developed worsened hemiparesis. In all four patients, postthrombolysis head CT examinations were negative for hemorrhage; CT angiogram showed patent cervical and intracranial arterial vasculature; CT perfusion imaging revealed hyperperfusion with increased relative cerebral blood flow and relative cerebral blood volume and decreased mean transit time along with decreased time to peak in the clinically related artery territory. Vascular dilation was also noted in three of these four cases. Conclusions. CHS should be considered in patients with clinical deterioration after iv tPA and imaging negative for hemorrhage. Cerebral angiogram and perfusion studies can be useful in diagnosing CHS thereby helping with further management. Yi Zhang, Abhay Kumar, John B. Tezel, and Yihua Zhou Copyright © 2016 Yi Zhang et al.

Sat, 30 Apr 2016 13:37:51 +0000 Miller-Fisher syndrome (MFS) is considered as a variant of the Guillain-Barre syndrome (GBS) and its characteristic clinical features are ophthalmoplegia, ataxia, and areflexia. Typically, it is associated with anti-GQ1b antibodies; however, a significant percentage (>10%) of these patients are seronegative. Here, we report a 67-year-old female patient who presented with the typical clinical features of MFS. Workup revealed antibodies against glutamic acid decarboxylase (GAD) in relatively high titers while GQ1b antibodies were negative. Neurological improvement was observed after intravenous gamma globulin and follow-up examinations showed a continuous clinical amelioration with simultaneous decline of anti-GAD levels which finally returned to normal values. This case indicates that anti-GAD antibodies may be associated with a broader clinical spectrum and future studies in GQ1b-seronegative patients could determine ultimately their clinical and pathogenetic significance in this syndrome.

Neurological Complications of Middle East Respiratory Syndrome Coronavirus: A Report of Two Cases and Review of the Literature Thu, 28 Apr 2016 06:20:12 +0000 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) was first discovered in September 2012 in Saudi Arabia. Since then, it caused more than 1600 laboratory-confirmed cases and more than 580 deaths among them. The clinical course of the disease ranges from asymptomatic infection to severe lower respiratory tract illness with multiorgan involvement and death. The disease can cause pulmonary, renal, hematological, and gastrointestinal complications. In this paper, we report neurological complications of MERS-CoV in two adult patients, and we hypothesize the pathophysiology. The first patient had an intracerebral hemorrhage as a result of thrombocytopenia, disseminated intravascular coagulation, and platelet dysfunction. The second case was a case of critical illness polyneuropathy complicating a long ICU stay. In these cases, the neurological complications were secondary to systemic complications and long ICU stay. Autopsy studies are needed to further understand the pathological mechanism. Hussein Algahtani, Ahmad Subahi, and Bader Shirah Copyright © 2016 Hussein Algahtani et al. All rights reserved. A Rare Case of Spontaneous Pneumocephalus Associated with Nontraumatic Cerebrospinal Fluid Leak Wed, 27 Apr 2016 14:25:00 +0000 Introduction. Spontaneous nontraumatic pneumocephalus (PNC) and cerebrospinal fluid (CSF) leaks are both very uncommon conditions. We report a rare case of spontaneous pneumocephalus associated with CSF leak secondary to right sphenoid sinus bony defect without history of trauma. Case Description. 51-year-old Hispanic female with past medical history of hypertension and idiopathic intracranial hypertension (Pseudotumor Cerebri) presented to the emergency room complaining of headache and clear discharge from the right nostril. Physical examination was significant for right frontal sinus tenderness and clear discharge from right nostril. Computed Tomography (CT) scan of the brain showed moderate amount of extra-axial air within the right cerebral hemisphere indicative of pneumocephalus. CT scan of facial bones showed bony defect along the right sphenoid sinus with abnormal CSF collection. The patient was started on intravenous antibiotics for meningitis prophylaxis and subsequently underwent transsphenoidal repair of cerebrospinal fluid leak with abdominal fat graft. CSF rhinorrhea stopped completely after the surgery with near complete resolution of pneumocephalus before discharge. Conclusions. Early identification of pneumocephalus and surgical intervention can help decrease the morbidity and avoid possible complications. Idiopathic intracranial hypertension, although rare, can lead to CSF leak and pneumocepahlus. Murad Baba, Omer Tarar, and Amer Syed Copyright © 2016 Murad Baba et al. All rights reserved. An Unusual Case of Asystole Occurring during Deep Brain Stimulation Surgery Wed, 27 Apr 2016 06:37:47 +0000 Background. Symptomatic bradycardia and hypotension in neurosurgery can produce severe consequences if not managed appropriately. The literature is scarce regarding its occurrence during deep brain stimulation (DBS) surgery. Case Presentation. A 67-year-old female presented for left DBS lead placement for essential tremors. During lead implantation, heart rate and blood pressure dropped rapidly; the patient became unresponsive and asystolic. Chest compressions were initiated and epinephrine was given. Within 30 seconds, the patient became hemodynamically stable and conscious. A head CT demonstrated no acute findings. After deliberation, a decision was made to complete the procedure. Assuming the etiology of the episode was the Bezold-Jarisch reflex (BJR), appropriate accommodations were made. The procedure was completed uneventfully. Conclusion. The episode was consistent with a manifestation of the BJR. The patient had a history of neurocardiogenic syncope and a relatively low-volume state, factors prone to the BJR. Overall, lead implantation can still occur safely if preventive measures are employed. Ha Son Nguyen, Harvey Woehlck, and Peter Pahapill Copyright © 2016 Ha Son Nguyen et al. All rights reserved. Endoport-Assisted Microsurgical Treatment of a Ruptured Periventricular Aneurysm Tue, 19 Apr 2016 10:56:02 +0000 Background and Importance. Ruptured periventricular aneurysms in patients with moyamoya disease represent challenging pathologies. The most common methods of treatment include endovascular embolization and microsurgical clipping. However, rare cases arise in which the location and anatomy of the aneurysm make these treatment modalities particularly challenging. Clinical Presentation. We report a case of a 34-year-old female with moyamoya disease who presented with intraventricular hemorrhage. CT angiography and digital subtraction angiography revealed an aneurysm located in the wall of the atrium of the right lateral ventricle. Distal endovascular access was not possible, and embolization risked the sacrifice of arteries supplying critical brain parenchyma. Using the BrainPath endoport system, the aneurysm was able to be accessed. Since the fusiform architecture of the aneurysm prevented clip placement, the aneurysm was ligated with electrocautery. Conclusion. We demonstrate the feasibility of endoport-assisted approach for minimally invasive access and treatment of uncommon, distally located aneurysms. Ching-Jen Chen, James Caruso, Robert M.

Profound Autonomic Instability Complicated by Multiple Episodes of Cardiac Asystole and Refractory Bradycardia in a Patient with Anti-NMDA Encephalitis Sun, 17 Apr 2016 10:22:40 +0000 Anti-N-methyl-D-aspartate receptor encephalitis (anti-NMDARE) is autoimmune encephalitis primarily affecting young adults and children. First described about a decade ago, it frequently manifests as a syndrome that includes progressive behavioral changes, psychosis, central hypoventilation, seizures, and autonomic instability. Although cardiac arrhythmias often accompany anti-NMDARE, the need for long-term electrophysiological support is rare. We describe the case of NMDARE whose ICU course was complicated by progressively worsening episodes of tachyarrhythmia-bradyarrhythmia and episodes of asystole from which she was successfully resuscitated. Her life-threatening episodes of autonomic instability were successfully controlled only after the placement of a permanent pacemaker during her ICU stay. She made a clinical recovery and was discharged to a skilled nursing facility after a protracted hospital course. Stephanie R. Mehr, Roy C. Neeley, Melissa Wiley, and Avinash B.
