A rare case of Mollaret meningitis characterized by four recurrent episodes of aseptic meningitis during the 3-year periods were reported. The patient showed high fever and severe headache accompanied by high level of cerebrospinal fluid (CSF) cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alfa (TNF-a). The symptoms and high CSF cytokines were dramatically resolved immediately after inducing indomethacin treatment. Reactivation of the latent virus is considered to be the cause of this rare disease and indomethacin is estimated to inhibit periodic abnormal generation of eicosanoid in the brain resulting in reducing fever and subsequent inflammation.
