Introduction
EBV infection is commonly characterized by fever, malaise, sore throat, upper respiratory symptoms, headache, and lymphadenopathy. CNS involvement is uncommon, occurring in 0.5-7.5% of all EBV infections [1], and can present with a wide spectrum of symptoms, including encephalitis, meningitis, myelitis, cranial neuropathy, mononeuritis multiplex, brachial plexopathy, acute psychosis, Guillain Barré syndrome, to acute cerebellar ataxia or seizures [1-3]. These neurological symptoms usually manifest 1-3 weeks after the onset of respiratory symptoms [1,4] but could also manifest much later, as in the case of our patient. Interestingly, EBV-related CNS infection tends to occur in younger adults, with an average age of 36, as reported in Japan [4]. We report a case of EBV-associated CNS infection in an immunocompetent adult.
