A 17-year-old man with severe sore throat and poor oral intake admitted for intractable tonsillitis had sore throat ameliorated, but vomiting, nausea and cerebellar ataxia occurred on day 5 after admission. Laboratary examination showed that EBV (VCA) IgM was positive and EBV nuclear antigen (EBNA) was negative, yielding a diagnosis of acute cerebellitis with initial EBV infection. Methylprednisolone pulse therapy ameliorated subjective symptoms a month after onset, optokinetic nystagmus test results did not improve. We found the equilibrium function test very useful in evaluating latent cerebellar disorder.
