Metropolitan W135 meningococcal compressive pericarditis treated with intrapericardial fibrinolysis.

Meningococcal pericarditis is a rare but severe form of acute purulent pericarditis. It is a classic complication of Neisseria meningitidis of serotype W135, usually occurring in pilgrims to Mecca and their household contacts. This severe form of meningococcaemia is difficult to diagnose and evolves frequently and gradually towards a tamponade, requiring emergency drainage. We report a case of meningococcal pericarditis caused by N. meningitidis W135 in an immunocompetent patient, without any other organ involvement especially meningeal, requiring pericardium drainage in emergency and then intrapericardial fibrinolysis.
