A pneumococcal purulent pericarditis revealing a pneumonia and complicated by an acute cardiac tamponade.

Purulent pericarditis secondary to pneumococcal pneumonia is a rare entity, and often underestimated despite being associated with a high mortality rate. We report a case of a man who developed a cardiac tamponade related to a previously unknown pneumococcal pneumonia. In conclusion, we emphasize the need of repeated clinical and echocardiographic exams.
