Abstract: Abstract：Benign recurrent aseptic meningitis is also known as Mollaret meningitis (MM). MM is a syndrome characterized by recurrent bouts of meningitis including recurrent headaches, nuchal rigidity, fever, and increased cells in cerebrospinal fluid. MM was first reported by Mollaret in 1944. It is a rare disease of central nervous system. One case of benign recurrent aseptic meningitis was hospitalized and treated in our department. The result of lumbar puncture showed no evidence of bacterial growth. Enhanced magnetic resonance imaging (MRI) showed high signal of meninges, suggesting that more attention should be paid to the application of enhanced MRI in the individual diagnosis of MM.

Key words: meningitis, aseptic, magnetic resonance imaging, spinal puncture, Mollaret meningitis
