Case summary This report involves a 10-year-old male mixed-breed cat with a B-cell central nervous system (CNS) lymphoma. The cat presented with ataxia progressing to left hemiparesis. While haematological findings were normal, serum biochemistry showed a high creatine phosphokinase concentration. MRI revealed a homogeneously enhancing well-demarcated extra-axial lesion involving the region of ...

we report a patient diagnosed with whipple's disease (wd) who presented only with neurological symptoms. neuroimaging (mri) showed lesions with marked mass effect similar to infiltrative tumors, which were hypersignal on long tr and hyposignal on short tr images, located in several areas of the brain. in serial controls, lesions resolved with gliosis and atrophic changes as well as migration of...

Multiple Sclerosis (MS) is an inflammatory disease of the Central Nervous System (CNS) that causes the demyelination of nerve cells and destroys oligodendrocytes, neurons and axons. Historically, MS has been thought of as a T cell-mediated autoimmune disease of CNS white matter. However, recent studies have identified gray matter lesions in MS patients, suggesting that CNS antigens other than m...

Multiple sclerosis is a demyelinating disorder of the central nervous system (CNS), in which an immune attack directed against myelin constituents causes myelin destruction and death of oligodendrocytes, the myelin-producing cells. Here, the efficacy of nerve growth factor (NGF), a growth factor for neurons and oligodendrocytes, in promoting myelin repair was evaluated using the demyelinating m...

BACKGROUND AND PURPOSE The safety and efficacy of Onyx for the embolization of central nervous system (CNS) arteriovenous (AV) lesions have been widely reported in adults. However, data describing the use of this agent in children are limited. This study presents our experience with Onyx in the treatment of CNS AV lesions in pediatric patients. MATERIALS AND METHODS We retrospectively analyze...

BACKGROUND Central nervous system (CNS) tuberculoma is a rare disease with severe neurological deficits. This retrospective research is to review the data of patients diagnosed as CNS tuberculoma. Surgeries were performed in all patients. The clinical features especially the neurological image and the anatomical characters of the tuberculomas were concerned. METHODS Totally 11 patients diagno...

A 73-year-old male presented with diffuse mixed B cell lymphoma with involvement of the central nervous system (CNS) and testis manifesting as mild disorientation and aphasia. A left frontal cerebral mass and a right testicular tumor were found, and both lesions were surgically resected. Histological examination revealed diffuse mixed B cell type malignant lymphoma in the CNS and testis. The pa...

Chronic oligodendrocyte loss, which occurs in the demyelinating disorder multiple sclerosis (MS), contributes to axonal dysfunction and neurodegeneration. Current therapies are able to reduce MS severity, but do not prevent transition into the progressive phase of the disease, which is characterized by chronic neurodegeneration. Therefore, pharmacological compounds that promote oligodendrocyte ...

Electrophysiological methods such as electroencephalography and evoked potential studies (EEG and EPs) provide functional assessment of the central nervous system (CNS). As such, their scope parallels that of the clinical examination and is complementary to that of imaging techniques (CT scan, MRI), which provide structural assessment. Indeed, CNS dysfunction may occur with or without evidence ...

BACKGROUND Central nervous system (CNS) involvement with Blastomyces dermatitidis is an uncommon and potentially fatal complication of blastomycosis. METHODS We retrospectively reviewed 22 patients with CNS blastomycosis at our institutions from 1990 through 2008 (13 proven, 5 probable, and 4 possible cases). RESULTS Magnetic resonance imaging was used in most patients, alone or in addition...
