title: A case of benign recurrent meningitis of Mollaret.
abstract: A 72-year-old woman, previously in good health, suffered for 2 years from attacks of a complex neuropsychiatric syndrome lasting from 2 days to 4 weeks. These episodes, which were followed by intervals of nearly complete recovery, were usually marked by fever, headache, mental confusion, vomiting ataxia, anisocoria, epileptic seizures and stiffness of the neck. Neuroradiological investigation revealed only slight ventricular dilatation. In 13 CSF examinations, there was reduced glucose, increased protein, considerable rise of the IgG index and constant oligoclonal bands. There was also an increase of polymorphonuclear leucocytes, lymphocytes or epithelial-like cells. As all microbial, viral or mycotic tests were negative and the patient recovered, the case was considered to be benign recurrent meningitis of Mollaret. The nosological position of this rare disease, as well as its probable pathogenetic mechanisms, are discussed.
