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.
