Nonneoplastic demyelinating processes of the brain with mass effect on magnetic resonance imaging can cause diagnostic difficulties. It requires differential diagnosis between the tumefactive demyelinating lesion and the coexistence of neoplasm. We document the case of 41-year-old woman with clinical and radiological findings suggestive of multiple sclerosis. Additional investigations confirmed...

Creutzfeldt-Jakob disease (CJD) is a relentlessly progressive neurodegenerative disorder, belonging to the transmissible spongiform encephalopathies. It is characterized by the deposition of the abnormal isoform of the prion protein (PrP), causing spongiform neurodegeneration. The disease is classically known to mainly affect the gray matter of the CNS. However, involvement of the peripheral ne...

Canine distemper virus (CDV) has been postulated to play a role in multiple sclerosis (MS), primarily on the basis of epidemiological evidence that has never been confirmed. However, this anecdotal association is still made by physicians and veterinarians. Although morbilliviruses such as CDV and measles virus (MV) potentially use the same cell surface receptor, CDV and others animal morbillivi...

Experimental allergic encephalomyelitis, a demyelinating disease with marked similarity to multiple sclerosis, was produced in two of 12 dogs. All dogs were studied with serial MR imaging. T1- and T2-weighted MR images were obtained both before and after IV Gd-DTPA. Multiple, new periventricular white matter demyelinating lesions were observed after each clinical episode of the disease. Like mu...

INTRODUCTION We report three cases of demyelinating disease with tumor-like presentation. This information is particularly important to both neurosurgeons and neurologists who should be aware that inflammatory demyelinating diseases can present as a mass lesion, which is indistinguishable from a tumor, both clinically and radiologically, especially when there is no evidence of temporal dissemin...

multiple sclerosis (ms) is a demyelinating disease of the central nervous system,with unknown etiology in which both genetic and environmental factors are thought to be involved. the hla system provides a set of genetic markers which lend themselves to systematic study. the disease also has variable clinical manifestations, ranging from a relapsing-remitting course to a chronic progressive dise...

demyelinating diseases of the central nervous system (cns) are a group of autoimmune disorders affecting the myelin sheets of cns neurons resulting in different neurological deficits and disability. multiple sclerosis (ms), devic’s disease, progressive multifocal leukoencephalopathy, acute disseminated encephalomyelitis (adem), and neuromyelitis optica (nmo) are among the most common types of d...
