brain, spinal cord, and nerve disorders
Recurrent Meningitis
Other causes
Recurrent meningitis may also be caused by conditions that are not infections (see table Some Causes of Noninfectious Meningitis ), such as use of nonsteroidal anti-inflammatory drugs (NSAIDs) or another drug. If one episode of meningitis was caused by a drug, meningitis may recur if people take the drug again. Meningitis caused by rupture of a brain cyst may also recur. These cysts are diagnosed by magnetic resonance imaging (MRI) of the brain and/or spinal cord or, if MRI is unavailable, computed tomography (CT).
