[Mollaret's meningitis. A rare disease with a characteristic presentation]

Abstract

We report a case of a 72-year-old woman, who within a six-year period had four episodes of Mollaret's meningitis. Lumbar punctures during each episode revealed moderate leukocytosis with large mononuclear cells. Characteristic manifestations and differential diagnosis are briefly reviewed. There is no established therapy for Mollaret's meningitis. Extensive investigations failed to reveal a specific cause of this disease, although there is some evidence for infection caused by Herpes simplex-virus.
