Extrameningial manifestations in patients with meningococcal meningitis are rare. One of these manifestations is immune-mediated or purulent pericarditis. We present a case where a patient with meningococcal meningitis developed pericarditis on the 11th day after admission. A pericardial puncture was performed but the pericardial fluid regenerated after two days despite antibiotic treatment. The pericardial fluid showed no bacterial growth and PCR for bacterial DNA was negative. Subsequent steroid treatment proved to be effective, indicating a case of immune-mediated pericarditis.
