[Acute cerebellitis caused by Epstein-Barr virus: case report].

Acute cerebellitis can occur in association with varicella-zoster virus, enterovirus, mumps, mycoplasma, and other infective organisms. Acute cerebellitis is a rare complication of Epstein-Barr virus (EBV) infection. We report the case of a 21-year-old woman with a 12-day history of nausea and vomiting, gait and limbs ataxia, myoclonus, tremor of head and all four limbs, opsoclonus and cutaneous rash. Anti-EBV IgG and IgM antibodies against antiviral capsid were positive and anti-EBV against virus-associated nuclear antigen was also positive. EBV infection in association with neurological findings can occur without the classic signs and symptoms of infectious mononucleosis.
