[Post-infectious Epstein-Barr virus encephalitis].

A case of meningoencephalitis is reported in a 14 year old boy. After an acute onset with fever and coma, the outcome was rapidly favorable. Antibody titers in acute and convalescent sera demonstrated recent infection with EBV. EBV encephalitis appears to be a post-infectious encephalitis with no direct viral invasion of the CNS and no acute viral replication.
