Abstract
To the Editor: A 32-year-old man was admitted to the hospital with signs and symptoms of an acute Central-nervous-system (CNS) infection. He had no history of recent genital infection, but two months earlier he had been treated with prostatic massage for painful erections. On admission he was febrile, hyperirritable, and disoriented. The cerebrospinal fluid (CFS) contained 10 mononuclear cells per cubic millimeter. Electroencephalography indicated a diffuse inflammatory process. The CNS symptoms subsided after two to three days but were followed by a slowly resolving bilateral arthritis of the knee and ankle joints.Extensive investigations for agents known to cause meningoencephalitis . . .
