[Psychopathological symptoms in atypical viral hemorrhagic tick-borne encephalitis].

A 17 year old boy was admitted because of symptoms of a catatonic syndrome. During the diagnosis we ascertained that there was bleeding from the central nervous system of unknown origin. The intensification of neurological and general symptoms/among others-hyperthermia/suggested haemorrhagic encephalitis, which was confirmed by the viral investigation of the cerebrospinal fluid (tick-borne encephalitis). We describe this case because viral encephalitis rarely has haemorrhagic effects. Usually tick-borne encephalitis is of diphasic type with the attacks of "epilepsia partialis continua", which were not observed in this case.
