A patient who initially presented with clinical and laboratory signs of bacterial meningitis developed four more similar episodes within a 6-month period. Immune system studies were unremarkable. A tentative diagnosis of Mollaret's meningitis was established after the third episode. Cranial computed tomography performed during the acute phase of the initial episode was normal, but, after the fourth scan, when the patient was asymptomatic, magnetic resonance imaging revealed a cyst in the anterior aspect of the medulla. Partial excision allowed for pathologic analysis, which established the diagnosis of epidermoid cyst. The differential diagnosis of recurrent aseptic meningitis should include Mollaret's meningitis and dermoid-epidermoid cysts. Neuroimaging studies, preferably magnetic resonance imaging, should be performed at a time when patients are asymptomatic.

Mollaret meningitis, a benign recurrent aseptic disease, is known to be associated with intracranial epidermoid cysts. In this report, we describe a case of Mollaret meningitis caused by an intraspinal epidermoid cyst located at thoracic level 12. The patient's clinical manifestations and cerebrospinal fluid features were similar to those with bacterial meningitis characterized by predominant polymorphonuclear leukocytes. However, Mollaret cells, not bacteria, were identified in the patient's cerebrospinal fluid. The illness ceased after surgical resection of the cyst, and the cyst tissue was pathologically diagnosed as epidermoid. Therefore, an intraspinal epidermoid cyst can be etiologically associated with Mollaret meningitis and should be included in the differential diagnosis of recurrent aseptic meningitis.
