[Mollaret benign recurrent aseptic meningitis. Case report, results of cerebrospinal fluid cytology and review of the literature].

Mollaret's recurrent aseptic meningitis is a rare disease of unknown etiology and excellent prognosis, characterized by short attacks of meningeal irritation, fever and pleocytosis with first polymorphonuclear, then mononuclear predominance. A case is reported, in which the characteristic so-called endothelial cells in the CSF were identified as monocytes with immunocytochemic methods. The remaining fraction of CSF cells mainly consisted of T-lymphocytes with a majority of CD4 positive cells and an increased portion of CD38 positive cells. Between attacks, patients are asymptomatic. The course is self-limiting. Specific treatment is unknown.
