Herpes simplex virus type II meningoencephalitis in an immunocompromised adult

A 35-year-old man with chronic granulocytic leukemia had disseminated herpes simplex virus type II. Cerebrospinal fluid pleocytosis, aphasia, and an abnormal electroencephalogram suggested the diagnosis of meningoencephalitis. He was treated with adenosine arabinoside and recovered without clinically evident sequelae.
