Sulindac-induced aseptic meningitis in mixed connective tissue disease.

A 21-year-old female with mixed connective tissue disease (MCTD) experienced nausea, headache, consciousness disturbance, nuchal rigidity, and a temperature of 38.5 less than or equal to C three days after the intake of sulindac (300 mg/day). Cerebrospinal fluid analysis revealed an opening pressure of 310 mm of water, a predominantly lymphocytic pleocytosis, and elevated protein content of 89 mg/dl. After discontinuing sulindac, the aseptic meningitis improved in five days. In the acute stage, CT scan disclosed contrast enhancement in the cerebral hemispheres, which suggests that hypersensitivity may be involved in the pathogenesis of nonsteroidal antiinflammatory drug (NSAID) induced aseptic meningitis.
