[Spinal segmental myoclonus in multiple sclerosis (case report)]. / Spinal'naia segmentarnaia miokloniia pri rasseiannom skleroze (nabliudenie iz praktiki).

Multiple sclerosis (MS) is a disease with multicentric lesions of central nervous system. These numerous lesions can cause a lot of different symptoms. Sometimes these signs are atypical and make difficulties for MS diagnosing. Hyperkinesis is extremely rare manifestation of MS especially if it concerns spinal myoclonus. Spinal myoclonic jerks can be caused by various focal damages of neuraxis including demyelination lesions. This report describes the case of spinal segmental myoclonus as an unusual manifestation of MS. The patient was diagnosed definite MS according to the McDonald criteria (2010). The nature of movement disorders was defined by careful neurologic and neurophysiologic examination. These movement disorders were reliably caused by demyelinating type lesions in the cervical cord.

[The chronic form of tick-born encephalitis with a clinical manifestation of disseminated encephalomyelitis (case description)].

In most cases, the chronic form of tick-born encephalitis (CTBE) develops after the acute phase of the disease and is characterized by polymorphic clinical manifestations. It is not often to see patients with disseminated encephalomyelitis in case of CTBE. We describe a patient with CTBE developed 12 years after the acute phase of the disease, which had a remitting course and clinically revealed multifocal lesions. MRI lesions did not differ from those caused by multiple sclerosis and the differential diagnosis of the latter was performed. The analysis of epidemiological data as well as the standard neurological examination in combination with the laboratory diagnostic methods allowed us to confirm the diagnosis of CTBE.
