Gliosarcoma with Primary Skull Base Invasion Thu, 08 Dec 2016 08:36:52 +0000 http://www.hindawi.com/journals/crira/2016/1762195/ Gliosarcoma is an uncommon variant of glioblastoma, which commonly demonstrates dural attachment. However, skull base invasion is rarely seen with this entity. Herein, we report a 44-year-old female patient diagnosed with primary intracranial gliosarcoma extensively invading the skull base and muscles of mastication. She presented to our institution with a three-month history of difficult right jaw opening and retro-orbital pressure and one week of severe right-sided postauricular headache. Head CT demonstrated a 6 cm mass with marked bony erosion. Brain MRI at a one-week interval more clearly characterized tumor extension through the right orbit and muscles of mastication, with overall growth to 7 cm and worsening midline shift. The patient underwent a right frontotemporal craniotomy for gross total resection. Pathology confirmed the diagnosis of gliosarcoma, IDH-wildtype (WHO grade IV). Her postoperative course was uneventful and she was discharged at preoperative neurologic baseline. To our knowledge, this is the third reported case of a primary intracranial gliosarcoma with direct invasion of skull base, brain parenchyma, and extracranial compartment. However, this is the first report case of primary GS invading the surrounding musculature and orbit. This case report highlights the rapid aggressiveness of gliosarcomas and further a prior undescribed radiographic and anatomic finding of skull base invasion with this entity. Quoc-Bao D.

Untreated Superior Vena Cava Aneurysm: Radiological Significance and Review of the Literature Mon, 05 Dec 2016 09:38:47 +0000 http://www.hindawi.com/journals/crira/2016/6960757/ Superior vena cava (SVC) aneurysms are a rare entity. The majority of the literature is in the form of case reports. SVC aneurysms are often an incidental finding with iatrogenic, congenital, or idiopathic etiologies. Treatment goals focus on preventing theoretical rupture or thrombus formation. Management options include observation, conservative medical management, surgical excision, and thrombin injection. We present a 73-year-old female with an incidental SVC aneurysm discovered on computed tomography (CT) of the thorax. The patient was observed without intervention for greater than 6 years. No complications were attributable to the SVC aneurysm during follow-up or over the course of the patient’s life.

Thymic Epidermoid Cyst: Clinical and Imaging Manifestations of This Rare Anterior Mediastinal Mass Thu, 24 Nov 2016 12:17:33 +0000 http://www.hindawi.com/journals/crira/2016/5789321/ Thymic epidermoid cysts are an extremely rare entity. These arise from epidermal cells that migrate to the thymus. The radiologic diagnosis of this rare lesion is challenging. We describe a case of an otherwise healthy 35-year-old woman who presented with an acute onset of chest pain and shortness of breath. She was found to have an anterior mediastinal mass. The imaging findings were, however, not characteristic for any single diagnostic entity. Since the imaging was inconclusive, surgical resection was performed for definitive diagnosis. The mass was found to be a thymic epidermoid cyst. This case underlines the significance for radiologists to be aware that epidermoid cysts can occur in the thymus and should be considered in the differential diagnosis for a heterogeneous anterior mediastinal mass.

Occipital Hypometabolism on FDG PET/CT Scan in a Child with Hodgkin’s Lymphoma Mon, 14 Nov 2016 12:06:07 +0000 http://www.hindawi.com/journals/crira/2016/5476108/ It is known that Fluorodeoxyglucose (FDG) Positron Emission/Computed Tomography (PET/CT) images may be helpful for evaluation of brain function in newborns. Here we described the fluorine-18 [18-F] FDG PET/CT imaging findings of encephalomalacia due to perinatal asphyxia in a child with refractory Hodgkin’s Lymphoma (HL) who underwent PET/CT scan to stage the primary disease. Prominent hypometabolism was incidentally detected in the occipital regions bilaterally apart from the FDG uptakes in the malign lymphatic infiltrations. This case highlights the potential coexistence of a malignancy and a functional brain disorder.

Rare Case of Posterior Reversible Leukoencephalopathy Syndrome Secondary to Acute Chest Syndrome Thu, 10 Nov 2016 08:41:00 +0000 http://www.hindawi.com/journals/crira/2016/4346953/ We present a case of 29/m with a history of sickle cell disease who presented to the emergency department with sudden onset of chest, trunk, extremity, and back pain, consistent in quality and severity with the patient’s usual pain crises. Soon after admission to the medical unit for acute chest syndrome (ACS), the patient developed sudden onset of hypertension associated with left sided hemiplegia, lethargy, dysarthria, aphasia, and left sided facial droop. Neuroimaging revealed that on MRI Brain there was multifocal extensive signal abnormality and a small focal areas of hemorrhage compatible with posterior reversible leukoencephalopathy syndrome (PRES). Patient was treated with levetiracetam and phenytoin and improved soon afterwards, with resolution seen on follow-up MRI two months later.

Internal Jugular Vein Thrombosis in Isolated Tuberculous Cervical Lymphadenopathy Wed, 09 Nov 2016 13:11:21 +0000 http://www.hindawi.com/journals/crira/2016/5184196/ Tuberculosis is a common infectious disease with a high prevalence in developing countries and presents a major public health issue. Internal jugular vein (IJV) thrombosis is a rare complication in tuberculous cervical lymphadenopathy. We report a case of 26-year male patient with a history of low-grade evening rise in fever, dry cough, loss of appetite, and loss of weight with swelling in lower neck on right side. Ultrasonography (USG) neck showed well-defined hypoechoic lymph nodes posterior to right IJV and common carotid artery in the lower neck at level IV and in the right supraclavicular region showing central necrotic areas with adjoining IJV thrombosis. The association between tuberculosis and deep vein thrombosis is rare. Awareness of IJV thrombosis in isolated cervical lymphadenopathy needs high diagnostic suspicion and prompt treatment to avoid fatal complication. Our case is rare as there was isolated tuberculous cervical lymphadenopathy with adjoining IJV thrombosis. Both USG and computed tomography (CT) are accurate and reliable radiological investigations for detecting IJV thrombosis along with cervical lymph nodes. They are useful in assessing surrounding soft tissue and fat planes and knowing the size and extent of cervical lymphadenopathy. USG is inexpensive and readily available for monitoring response to treatment.

Cardiac Magnetic Resonance for Evaluating Catheter Related FDG Avidity Thu, 27 Oct 2016 12:54:45 +0000 http://www.hindawi.com/journals/crira/2016/5460727/ A 53-year-old female with a history of metastatic left arm melanoma presented for F(18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) which showed a moderately FDG avid focus at her port catheter tip near the cavoatrial junction. Although catheter tip related FDG avidity has previously been suggested to be bland thrombus or infection, melanoma can metastasize to unusual locations including the superior vena cava. In addition, the patient had an elevated risk of anticoagulation due to a history of hemorrhagic brain metastases. Therefore, confirmatory cardiac magnetic resonance (CMR) was obtained and findings were consistent with bland catheter-related thrombus. Daniel Jeong, Kenneth L. Gage, Claudia G. Berman, and Jaime L.

Bilateral Simultaneous Pseudoangiomatous Stromal Hyperplasia of the Breasts and Axillae: Imaging Findings with Pathological and Clinical Correlation Thu, 27 Oct 2016 11:23:34 +0000 http://www.hindawi.com/journals/crira/2016/9084820/ Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a pathology that is usually diagnosed by accident during pathological examination of other breast lesions. PASH is an uncommon and benign tumoral lesion of the mammary stroma that can be pathologically mistaken for other tumours, such as phyllodes, fibroadenoma, and sometimes even angiosarcoma. We report the case of a 45-year-old woman with complaints of huge bilateral breast enlargement. This is a rare case of PASH presenting with gigantomastia and involving bilateral breasts and axillae simultaneously. Mammography, ultrasonography, and MRI features are illustrated with histopathological correlation.

Congenital Vitelline Band Causing Intestinal Obstruction in an Adult with a Double Inferior Vena Cava Sun, 23 Oct 2016 08:09:17 +0000 http://www.hindawi.com/journals/crira/2016/4015408/ Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckel’s diverticulum. Double inferior vena cava (IVC) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small outpouching in the distal ileum with a band like structure attached to it. In the CT, left sided patent IVC draining into the left renal vein was identified. Left external iliac vein was in continuity with the left IVC. Left internal iliac vein was draining into the right IVC. Exploratory laparotomy revealed a Meckel’s diverticulum with a band identified as the vitelline remnant attached to its apex and inserting at the anterior abdominal wall near the umbilicus. Discussion. Meckel’s diverticulum with vitelline bands, although rare, should be borne in mind in adult patients with intestinal obstruction. Identification of this anomaly can be difficult in imaging studies. Presence of double IVC should be mentioned in the imaging findings to prevent possible catastrophic complications during surgery.

Left-Sided Upper Partial Anomalous Pulmonary Venous Return through a Curved Vein Joining the Left Brachiocephalic Vein Sun, 09 Oct 2016 12:24:22 +0000 http://www.hindawi.com/journals/crira/2016/1780909/ The evaluation of pulmonary veins during cross-sectional imaging of the chest and the knowledge of their embryology and anatomy are useful for detecting congenital conditions that may be clinically significant. Moreover, with the spread of cross-sectional imaging it is very frequent to find anatomical variants; therefore the radiologist should easily recognize their appearances. This case report shows a left-side upper partial anomalous pulmonary venous return (PAPVR) through a “curved” vein that joins the left brachiocephalic vein, in a female patient who underwent whole-body computed tomography (CT) for staging endometrial cancer. This was an incidental finding, not related to any symptoms; however, we explain the anatomical aspects of this abnormality within the congenital condition of PAPVR and its possible clinical relevance.

Diagnosis and Management of Spontaneous Lumbar Venous Retroperitoneal Hematoma in Setting of Deep Venous Thrombosis: A Case Report and Algorithm Mon, 03 Oct 2016 14:18:30 +0000 http://www.hindawi.com/journals/crira/2016/3183985/ Retroperitoneal hematoma is rare and benefits from a systematic approach to prevent morbidity and mortality. Management of such bleeds is based upon patient stability, the cause (spontaneous or posttraumatic), and source (arterial or venous). Herein, the authors describe a diagnostic and management algorithm for retroperitoneal hemorrhage with an example of a rare lumbar venous bleed under the complicated clinical setting of deep venous thrombosis.

Atypical Growth Pattern of an Intraparenchymal Meningioma Mon, 26 Sep 2016 12:49:46 +0000 http://www.hindawi.com/journals/crira/2016/7985402/ Meningiomas are the most common primary nonneuroglial extra-axial neoplasms, which commonly present as spherical or oval masses with a dural attachment. Meningiomas without dural attachment are rare and, according to their locations, are classified into 5 varieties, including intraventricular, deep Sylvain fissure, pineal region, intraparenchymal, or subcortical meningiomas. To the best of our knowledge, intraparenchymal meningioma with cerebriform pattern has never been reported. In this paper, we report a 34-year-old Chinese male patient who presented with paroxysmal headaches and progressive loss of vision for 10 months and blindness for 2 weeks. A thorough physical examination revealed loss of bilateral direct and indirect light reflex. No other relevant medical history and neurologic deficits were noted. Computed tomography and magnetic resonance imaging scans showed an irregular mass with a unique cerebriform pattern and extensive peritumoral edema in the parietal-occipital-temporal region of the right cerebral hemisphere. The initial diagnosis was lymphoma. Intraoperatively, the tumor was completely buried in a sulcus in the parietal-occipital-temporal region without connecting to the dura. The histological diagnosis was intracranial meningioma based on pathological examination. Therefore, when an unusual cerebriform growth pattern of a tumor is encountered, an intraparenchymal meningioma should be considered as a differential diagnosis.

Intracranial Capillary Hemangioma in the Posterior Fossa of an Adult Male Thu, 22 Sep 2016 16:15:36 +0000 http://www.hindawi.com/journals/crira/2016/6434623/ Intracranial capillary hemangioma (ICH) is a rare entity, with approximately 24 reported cases in the literature. There are only three reported cases of ICH in an adult male. In this case report, we describe the fourth documented case of ICH in an adult male and, to the best of our knowledge, the first ever documented case of ICH in the posterior fossa of an adult male. We also discuss its imaging appearance and differential diagnosis. Jordan Nepute, Jinping Lai, and Yihua Zhou Copyright © 2016 Jordan Nepute et al. All rights reserved. Mediastinal Hibernoma: A Rare Case with Radiologic-Pathologic Correlation Mon, 29 Aug 2016 12:35:07 +0000 http://www.hindawi.com/journals/crira/2016/2378143/ Hibernomas, especially located in the mediastinum, are extremely rare benign tumors, which are important to consider in the differential diagnosis of a heterogeneously enhancing mass with areas of fat attenuation on imaging of an often incidentally discovered mass. Other common possibilities in the differential include malignant tumors, such as liposarcoma, hence histopathology is usually required to confirm the diagnosis. Hibernomas often follow the distribution of sites of persistence of brown fat in adults, and intrathoracic locations are unusual. We present a very rare case of a mediastinal hibernoma in a 53-year-old woman. She presented to the emergency department with severe, progressive right neck and shoulder pain with radiation down her arm and was found to have a right apical posterior mediastinal mass on imaging. Initial radiographs of the shoulder showed a soft tissue mass within the apical right hemithorax. Further imaging with CT revealed a well circumscribed, heterogeneously enhancing mass with areas of fat attenuation. Pathology confirmed the diagnosis of mediastinal hibernoma, and the mass was completely excised. Fourteen months after surgery, the patient had a normal chest radiograph, and thirty-two months after surgery, she remains asymptomatic. Maxine Darke, Anil Dasyam, Matthew Then, Kavita Varma, Amir A.

Tailgut Cyst and Perineal Hydatid Cyst: A Case Report with Multimodality Imaging Findings Wed, 17 Aug 2016 11:25:18 +0000 http://www.hindawi.com/journals/crira/2016/4212753/ A tailgut cyst is a rare developmental lesion and usually is located in the retrorectal or presacral space. Extrahepatic hydatid disease has been reported in several locations including the pelvis and it often poses a diagnostic challenge. There are very few reported cases of primary perineal hydatid cysts. We present the multimodality imaging findings of a tailgut cyst and concurrent perineal hydatid disease in a 32-year-old male patient. Ibtisam Musallam Aljohani, Khalefa Ali Alghofaily, Sebastian R.

Giant Cell Tumor of Bone: Documented Progression over 4 Years from Its Origin at the Metaphysis to the Articular Surface Wed, 17 Aug 2016 09:41:17 +0000 http://www.hindawi.com/journals/crira/2016/9786925/ The exact location of origin for giant cell tumors of bone (GCTB) remains controversial, as lesions are not routinely imaged early but rather late when the tumor is large and clinically symptomatic. At the time of diagnosis, GCTB are classically described as lucent, eccentric lesions with nonsclerotic margins, located within the epiphysis to a greater extent than the metaphysis. Here we present a case of a biopsy proven GCTB initially incidentally seen on MRI as a small strictly metaphyseal lesion, which over the course of several years expanded across a closed physis to involve the epiphysis and abut the articular surface/subchondral bone plate.

Fatal Meningitis in a 14-Month-Old with Currarino Triad Thu, 11 Aug 2016 10:49:29 +0000 http://www.hindawi.com/journals/crira/2016/1346895/ We report a case of a 14-month-old girl with undiagnosed Currarino triad presenting acutely with meningitis caused by enteric commensals. Head CT demonstrated a large pneumocephalus. A fistulous neurenteric tract through a presacral mass was present on spine MRI and abdominal CT. The patient had a history of constipation for the last three months. However, an underlying diagnosis of Currarino triad had not been suspected. In retrospect, a sickle-shaped sacral anomaly was present on a previous abdominal radiograph. The patient succumbed to complications of meningitis. The purpose of the case report is to highlight the potentially fatal complication of Currarino triad and sensitize radiologists to look actively for sacral anomalies on abdominal radiographs, especially of children with chronic constipation.

MRI Findings of Syndrome of Acute Bilateral Symmetrical Basal Ganglia Lesions in Diabetic Uremia: A Case Report and Literature Review Sun, 17 Jul 2016 12:32:45 +0000 http://www.hindawi.com/journals/crira/2016/2407219/ The syndrome of acute bilateral basal ganglia lesions is an uncommon clinical occurrence exhibiting acute onset of movement abnormalities, which can be seen almost exclusively among patients with chronic renal failure, especially in the setting of concurrent diabetes mellitus. Symmetrical lesions located in basal ganglia demonstrated in MRI are typical manifestation of this syndrome. Our study includes routine MRI examination, MRS, 3D-ASL, and SWI findings, which have been rarely reported and will contribute to diagnosing more cases about this syndrome.

Painful Os Peroneum Syndrome: Underdiagnosed Condition in the Lateral Midfoot Pain Tue, 05 Jul 2016 09:53:00 +0000 http://www.hindawi.com/journals/crira/2016/8739362/ Os peroneum is an accessory ossicle located within the peroneus longus tendon. The painful os peroneum syndrome (POPS) results from a wide spectrum of conditions, including fractures, diastases, and other causes. POPS can result in tenosynovitis or discontinuity of the peroneus longus tendon with a clinical presentation of pain in the lateral aspect of the midfoot. Authors report a typical case of POPS, illustrating this entity through different imaging methods (radiographs, ultrasound, and magnetic resonance imaging). We emphasize the prevalence of this ossicle and discuss painful complications.

Müllerian Remnant Cyst as a Cause of Acute Abdomen in a Female Patient with Müllerian Agenesis: Radiologic and Pathologic Findings Thu, 30 Jun 2016 14:17:50 +0000 http://www.hindawi.com/journals/crira/2016/6581387/ We report a case of a 17-year-old female with Müllerian agenesis who presented with right sided abdominal pain clinically suspicious for acute appendicitis. Multimodality imaging workup revealed a heterogeneous cystic right upper quadrant mass with surrounding fluid and inflammatory changes. Surgical resection of this mass was performed and a histopathologic diagnosis of a hemorrhagic Müllerian remnant cyst was made, which to the best of our knowledge has never been described in a patient with Müllerian agenesis.

Variant PTA Terminating in Cerebellar Artery, Associated with Multiple Aneurysms Thu, 30 Jun 2016 09:36:36 +0000 http://www.hindawi.com/journals/crira/2016/4594326/ Persistent trigeminal artery (PTA) is one of the remnant fetal anastomoses between the carotid artery and basilar artery. PTAs are classified according to angiographic appearance and various connection. Among them, those directly terminating in the cerebellar arteries are rare subtype. In addition, aneurysms of the PTA are unusual in the literature and have not previously accompanied this subtype of PTA connecting cerebellar artery. We present the first case of an aneurysm of the PTA which is directly terminating in the cerebellar arteries and combined with multiple aneurysms.

Fractured Ribs and the CT Funky Fat Sign of Diaphragmatic Rupture Sun, 26 Jun 2016 10:55:40 +0000 http://www.hindawi.com/journals/crira/2016/6723632/ Traumatic diaphragmatic rupture remains a diagnostic challenge for both radiologists and surgeons. In recent years, multidetector CT has markedly improved the diagnosis of diaphragmatic injury in polytrauma patients. Herein, we describe two cases of subacute presentation of traumatic diaphragmatic rupture from a penetrating rib fracture and subsequent intrathoracic herniation of omental fat, representing the CT “funky fat” sign.

Solitary Spinal Epidural Metastasis from Prostatic Small Cell Carcinoma Thu, 16 Jun 2016 11:56:23 +0000 http://www.hindawi.com/journals/crira/2016/4728343/ Solitary, spinal epidural metastasis (SEM) that is not related to vertebral metastasis is very rare. And solitary SEM from prostatic cancer is rarely found in previously published reports. However, it is clinically significant due to the possibility of neurologic dysfunction, and it can be assessed by MRI. In this report, we show a case of solitary SEM arising from prostatic small cell carcinoma detected by MRI. Kyung Ryeol Lee and Young Hee Maeng Copyright © 2016 Kyung Ryeol Lee and Young Hee Maeng.

Bilateral Morgagni Hernia: A Unique Presentation of a Rare Pathology Tue, 14 Jun 2016 11:22:50 +0000 http://www.hindawi.com/journals/crira/2016/7505329/ Morgagni hernia is an unusual congenital herniation of abdominal content through the triangular parasternal gaps of the anterior diaphragm. They are commonly asymptomatic and right-sided. We present a case of a bilateral Morgagni hernia resulting in delayed growth in a 10-month-old boy. The presentation was unique due to its bilateral nature and its symptomatic compression of the mediastinum. Diagnosis was made by 3D reconstructed CT angiogram. The patient underwent medical optimization until he was safely able to tolerate laparoscopic surgical repair of his hernia. Upon laparoscopy, the CT findings were confirmed and the hernia was repaired. Michael Leshen and Randy Richardson Copyright © 2016 Michael Leshen and Randy Richardson. All rights reserved. Traumatic Cardiac Injury: Ventricular Perforation Caught on CT Sun, 12 Jun 2016 11:33:44 +0000 http://www.hindawi.com/journals/crira/2016/9696107/ Myocardial rupture is a rare imaging diagnosis given its clinical severity and high mortality. Early findings should be promptly communicated to the trauma service to ensure immediate intervention. We present a rare case of blowout perforation of the right ventricle which was prospectively diagnosed on computed tomography (CT) leading to emergent operative repair. The patient subsequently survived and was discharged after a lengthy hospital course. Behrad Golshani, Paul Dong, and Scott Evans Copyright © 2016 Behrad Golshani et al. All rights reserved. Multifocal Head and Neck Neurofibromas with Osseous Abnormalities and Muscular Hypoplasia in a Child with Neurofibromatosis: Type I Sun, 12 Jun 2016 06:04:53 +0000 http://www.hindawi.com/journals/crira/2016/3980270/ Neurofibromatosis type 1 (NF1) is a clinically and genetically distinct disease involving both neuroectodermal and mesenchymal derivatives. Orofacial manifestations in NF1 have been documented before but occurrence of multifocal intraosseous (IO) and extraosseous (EO) neurofibromas is rare. The present case highlights the importance of imaging findings in the diagnosis and management of multifocal jaw, infratemporal, and parotid neurofibromas with muscular hypoplasia in an eight-year-old girl with NF1. Apart from orthopantomograms (OPG), three-dimensional computed tomography (3D CT) and cross-sectional reformations were valuable in delineating the extent of the lytic lesion and identifying additional bony deformities of the mandible. Magnetic resonance imaging (MRI) helped to identify the solid nature of the lesion and true extent of the soft tissue mass.

CT Findings of Axillary Tuberculosis Lymphadenitis: A Case Detected by Breast Cancer Screening Examination Thu, 09 Jun 2016 06:21:32 +0000 http://www.hindawi.com/journals/crira/2016/9016517/ We report the first description of CT findings of axillary tuberculous lymphadenitis confirmed by the pathological specimen. The breast cancer screening examination is one of the prime methods of detection of axillary tuberculous lymphadenitis. The most common site of axillary tuberculous lymphadenitis is the deep axilla. Screening mammography often fails to cover the whole axilla. The presence on the contrast-enhanced CT of unilateral multiple circumscribed dense nodes, some of which have large and dotted calcifications, might suggest tuberculous lymphadenitis in axillary region.

Endovascular Embolization of an Aberrant Bronchial Artery Originating from the Internal Mammary Artery in a Patient with Hemoptysis Tue, 07 Jun 2016 06:19:13 +0000 http://www.hindawi.com/journals/crira/2016/2707195/ Massive hemoptysis is a life threatening respiratory emergency with high mortality and the bronchial artery (BA) is its most frequent source. Herein, we report a case of a 76-year-old man with recurrent hemoptysis due to an aberrant right BA arising from the right internal mammary artery (IMA), an extremely rare origin, that was clearly depicted on pretreatment computed tomography angiography (CTA). The patient was treated successfully by transcatheter bronchial artery embolization (BAE) of the aberrant BA and the hemoptysis has since been controlled for 9 months. Knowledge of the detailed BA anatomy is essential for performing BAE, especially in cases of aberrant BA. CTA is a promising tool for pretreatment planning of emergency BAE in patients with hemoptysis.

Macroscopic Hematuria and a Bladder Mass: Eosinophilic Cystitis in a 7-Year-Old Boy Tue, 31 May 2016 13:45:16 +0000 http://www.hindawi.com/journals/crira/2016/9346218/ We report a case of eosinophilic cystitis in a 7-year-old boy with a history of atopic symptoms, with focus on the radiological findings. He presented with hematuria and dysuria and ultrasonography (US) showed irregular bladder wall thickening resembling a bladder mass. CT urography did not characterize the lesion any further and showed no local or distant spread. Biopsies revealed eosinophilic cystitis, a benign inflammatory condition. We found that US characterized the lesion at least as well as CT and should be the first choice of imaging. When staging is considered before biopsy, MRI should be preferred to CT. There are no specific radiological signs of eosinophilic cystitis. On follow-up, US was a safe, cost-effective imaging modality, but findings should be interpreted in a clinical context. In a child with hematuria and a bladder mass, eosinophilic cystitis is a relevant but rare differential diagnosis, especially when there is a known atopic history.

New Method of Parent Catheter Advancement in the Balloon Anchor Technique during Balloon-Occluded Transarterial Chemoembolization for Hepatic Tumors Tue, 31 May 2016 08:50:13 +0000 http://www.hindawi.com/journals/crira/2016/1957129/ Balloon-occluded transarterial chemoembolization (B-TACE) using a microballoon catheter is a promising method for improvement of lipiodol emulsion accumulation and local control relative to conventional transarterial chemoembolization. This method has been referred to as the balloon anchor technique in previous reports. We report a new technique for successful parent catheter advancement for achievement of stable backup for the selective insertion of a microballoon catheter during B-TACE using the microballoon as an anchor, even in patients with tortuous anatomy of the hepatic and celiac arteries. Deep cannulation of parent catheters was accomplished in all three cases and complications such as vascular injury were not observed in the postprocedure angiograms.
