Pericarditis complicating a case of meningococcal meningitis.

The case is described of an 18-year-old schoolboy who developed pericarditis during the course of meningococcal meningitis; he had evidence of a preceding chronic meningococcaemia. Good recovery followed on systemic antibiotics only. The pericarditis was probably a direct septic complication of meningococcal meningitis.
