Focal form of tickborne encephalitis affected by acute cerebrovascular disorders

Abstract

The relevance of the problem of tick-borne encephalitis (TBE) is explained by its vast geographical distribution and a wide variety of its clinical diseases, from inapparent (febrile) infections to severe meningoencephalitic forms leading to disability. In the Russian Far East, the infectious process of TBE with varying degrees of severity is caused by strains of the Far Eastern subtype only, which are variable in parameters of both biological and molecular-genetic characteristics and characterized by more severe and pronounced damage to the central nervous system. We present a unique case of polioencephalomyelitic TBE form, i.e., an initial progredient continuously progressive variant with the clinic of pronounced peripheral tetraparesis, paresis of shoulder girdle and diaphragm muscles, and lesions of cranial bulbar nerves (9, 10 and 12 pairs). The features of the clinic are explained by the patient's prolonged forced stay on artificial ventilation at the onset of acute cerebral circulatory failure.
