Mollaret Meningitis Associated with Occipital Dermal Sinus

Abstract

A 1-month-old female infant was referred with vomiting and fever. The cerebrospinal fluid (CSF) showed a pleocytosis (291 cells/mm3). Peripheral blood demonstrated leukocytosis (17 000/mm3) and high value of C-reactive protein (1.19 mg/dL). The culture results of CSF were negative. The patient was treated with antibiotics, and the symptoms resolved within 48 hours. One month later, she manifested a second episode of meningitis with pleocytosis in CSF (2506 cells/mm3). She was treated with antibiotics and dexamethasone, resulting in the resolution of meningitis within 24 hours.
