摘要

Sirs: Acute disseminated encephalomyelitis (ADEM) is an uncommon, acute demyelinating disorder of the central nervous system (CNS), usually monophasic and occurring after infections or vaccinations . Although a number of infectious agents seem to have a definite close implication in the pathogenesis of ADEM, isolated cases associated with hepatitis A virus (HAV) infection have been reported in children [1,8,11,12].A 29-year-old man with no history of neurological disease developed fever, headache, gait difficulty and urinary retention. Blood examinations revealed a high level of hepatic transaminases (1555 IU/L ALT, 540 IU/L AST) and a high titre of HAV IgM antibodies. In the following days he showed severe gait ataxia, bilateral pyramidal signs of the lower extremities, hypoesthesia with a sensory level at T10. Quantitative analysis of cerebrospinal fluid (CSF) was normal. Immuno-fixation with anti-IgG demonstrated the same band in the cathodic region of gamma-globulins both in serum and in CSF.
