Abstract
Multiple sclerosis (MS) is prominent among central nervous system diseases. It affects chiefly young people and almost inevitably results in disability. In the past decade, there has been an upward trend for the prevalence of MS worldwide; in particular, the higher prevalence of this disease has been registered in the Moscow Region, which is associated with both an objective increase in its morbidity and improvement of specialized care to the population in the region. MS is characterized by a variety of clinical manifestations. However, paroxysmal disturbances are referred to as the rare symptoms of MS: the incidence of epileptic seizures in this condition is 0.89 to 7.5% according to the literature data. In addition to the clinical form of MS, there are its rare malignant atypical forms that also include its pseudotumoral form characterized by intrinsic neuroimaging and clinical signs that are different from the classical form of MS and another abnormality of the central nervous system. The pseudotumoral form of MS is characterized by the development of acute focal demyelination that appears as a large focus of an increased magnetic resonance signal with perifocal edema as evidenced by magnetic resonance imaging. A pseudotumoral focus of demyelination can occur both at the onset of MS and during its recurrent course. The atypical onset of MS is a special challenge because of diagnostic problems, which may lead to erroneous therapeutic policy and have a negative impact on the late prognosis of the disease. The authors provide a clinical case of the pseudotumoral form of MS with convulsive seizures at the onset of demyelinating disease. The problems of diagnosis and therapeutic approaches are discussed.
