Giant cell ependymoma (GCE) is a rare primary CNS neoplasm. We report a case of GCE arising in the lateral ventricle. A 22-year-old female presented with generalized seizures. MRI demonstrated a diffuse, non-enhancing, multi-cystic mass centered in the atrium of the right lateral ventricle with extension throughout the frontal and temporal horns. An initial subtotal resection yielded the signature biphasic pattern of GCE. The dominant component contained pleomorphic, bizarre-appearing giant cells with low mitotic index, and a minor component comprised monomorphic, highly cellular, mitotically active cells that formed perivascular pseudorosettes...

The cystic cavity that develops following injuries to brain or spinal cord is a major obstacle for tissue repair in central nervous system (CNS). Here we report that injection of imidazole-poly(organophosphazenes) (I-5), a hydrogel with thermosensitive sol-gel transition behavior, almost completely eliminates cystic cavities in a clinically relevant rat spinal cord injury model. Cystic cavities are bridged by fibronectin-rich extracellular matrix. The fibrotic extracellular matrix remodeling is mediated by matrix metalloproteinase-9 expressed in macrophages within the fibrotic extracellular matrix...

An 11-year-old boy collapsed during morning assembly at his junior high school. The automated external defibrillator detected ventricular fibrillation and provided shock delivery. He was successfully resuscitated and reverted to sinus rhythm. Electrocardiography showed ST-T elevation in the precordial leads. Echocardiography and angiography demonstrated akinesia of the apex and mid-wall of the left ventricle with preserved contraction of the basal segments, which suggested Takotsubo cardiomyopathy. The patient and his family had often eaten uncooked crab, and his father had a past history of infection with Paragonimiasis westermani...

BACKGROUND: Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system, caused by the tapeworm Taenia solium. It is endemic to certain parts of the world, including Central America, South America, Asia, and Africa. The racemose form, characterized by extraparenchymal location, increased morbidity and mortality, and large loculated cystic lesions, is rarely seen in industrialized countries, such as the United States. The management of racemose neurocysticercosis (RNCC) differs from that of the typical parenchymal variant...

BACKGROUND: The most common lymphoid malignancy in adults is diffuse large B-cell lymphoma (DLBCL). The median age of occurrence of DLBCL is between 6(th) and 7(th) decade of life, although some other types of aggressive non-Hodgkin's lymphomas (NHL) are present in younger age. Primary central nervous system lymphoma (PCNSL) is an uncommon type of extranodal NHL, which is either more prevalent or is diagnosed more often than before. CASE DESCRIPTION: A 22-year-old man with ventriculoperitoneal shunt (VPS) performed at another center was referred with manifestations of shunt malfunction, unusual behavior, dysphasia, and hallucination...

Von Hippel-Lindau (VHL) disease is a rare autosomal dominant cancer syndrome caused by alterations of VHL gene. Patients are predisposed to develop pheochromocytomas and solid or cystic tumors of the central nervous system, kidney, pancreas, and retina. Remarkable phenotypic heterogeneity exits in organ involvement and tumor onset age between and within VHL families. However, no reliable markers have been found to predict the age-related tumor risks in VHL patients. A large Chinese cohort composed of 300 VHL patients and 92 healthy family controls was enrolled in our study...

Neuroectodermal developmental anomalies are reported rarely in cetaceans and central nervous system cysts are not described. We describe the gross, microscopical, histochemical and immunohistochemical features of a neuraxial myelencephalic cyst in a stranded neonatal Burmeister's porpoise (Phocoena spinipinnis). Grossly, a subdural, extra-axial, well-demarcated, yellow fluid-filled cystic structure (1.9 × 1.6 × 1 cm) expanded the left foramen of Luschka, the left caudolateral cerebellar recess and the left cranioventral myelencephalon...

Cystic brain metastases (CBM) have been recently reported in a minority of patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). All previously reported ALK-positive CBM developed during crizotinib treatment and were often asymptomatic and indolent, even without CNS-directed therapy. Thus, crizotinib was suggested as an etiologic agent for the development of CBM. Here, we report a case of de novo CBM in a patient with ALK-positive NSCLC prior to crizotinib treatment; the ALK-positive NSCLC had initially been misdiagnosed as neurocysticercosis because of the atypical radiological presentation of brain metastases...

The Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by the predisposition for multiple tumors caused by germline mutations in the tumor suppressor gene VHL. This disease is associated with a high morbidity and mortality and presents a variable expression, with different phenotypes from family to family, affecting different organs during the lifetime. The main manifestations of VHL are hemangioblastomas of the central nervous system and retina, renal carcinomas and cysts, bilateral pheochromocytomas, cystic and solid tumors of the pancreas, cystadenomas of the epididymis, and endolymphatic sac tumors...

BACKGROUND: Individuals with cystic fibrosis (CF) are at high risk for depression and anxiety, which are associated with worse medical outcomes. Novel therapies for CF hold great promise for improving physical health, but the effects of these therapies on mental health remain poorly understood. OBJECTIVE: This review aims to familiarize psychiatrists with the potential effect of novel CF therapies on depression and anxiety. METHODS: We discuss novel therapies that directly target the mutant CF protein, the CF transmembrane regulator (CFTR), which are called CFTR modulators...

BACKGROUND: Cystic fibrosis (CF) transmembrane regulator (CFTR) protein dysfunction causes CF. Improving survival allows detection of increasingly subtle disease manifestations. CFTR dysfunction in the central nervous system (CNS) may disturb circadian rhythm and thus sleep phase. We studied sleep in adults to better understand potential CNS CFTR dysfunction. METHODS: We recruited participants from April 2012 through April 2015 and administered the Munich Chronotype Questionnaire (MCTQ)...

The objective of this study was to analyze the characters of the cerebellopontine angle (CPA) metastases from central nerve system (CNS) tumors. Ten patients were reviewed for the period between 2008 and 2015. The clinical and neuroimaging features, and treatment outcomes were analyzed retrospectively. The average period during primary diagnosis through the diagnosis of CPA metastases was 42.4months. Among the 10 cases, the primary tumors and metastases were found simultaneously in 3 cases, the metastases after primary tumor removal were found in 5 cases, and the metastases after stereotaxic radiosurgery were found in 2 cases...

BACKGROUND: Rathke cleft cyst (RCC) is a rare cystic sellar entity, which is usually small in size and asymptomatic in most patients. RCC presenting panhypopituitarism and a cystic lesion with rim enhancement on magnetic resonance imaging is extremely rare. Therefore, it is easy to be misdiagnosed as pituitary abscess because of the similar clinical manifestations and neuroimaging changes. CASE SUMMARY: We report a rare case of RCC masquerading as pituitary abscess clinically and radiologically with no evidence of central nervous system infection...
