Meningococcal pericarditis and tamponade.

We report the case of a 37-year-old female with a complex manifestation of serogroup C meningococcal disease. The patient presented with symptoms and signs of pneumonia, sepsis and diffuse intravascular coagulation. Moreover, she suffered from a culture-proven pyogenic pericarditis that deteriorated into cardiac tamponade. Immediate pericardiocentesis was successful and eventually the patient recovered.
