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.
