[Two cases of pneumococcal pericarditis].
BACKGROUND: Bacterial pericarditis is often overlooked, partly because symptoms and signs associated with pericarditis are frequently missing, but also because of the rarity of the disease. MATERIAL AND METHODS: Two cases of pneumococcal pericarditis treated at Ullevaal University Hospital are presented. RESULTS: Pneumococcal pericarditis is a rare, but serious complication to infections like pneumonia, pleural empyema, and septicaemia. Patients with an infectious disease who develop signs of elevated central venous pressure, enlarged cardiac silhouette on chest x-ray, or severe hypotension should have an echocardiography performed. If pericardial fluid is present, a diagnostic pericardiocentesis should be considered. INTERPRETATION: Treatment consists of drainage and antibiotics. Pericardiocentesis and subxiphoid catheter drains may be inadequate because of fibrin precipitation resulting in organization of the fluid. In these cases surgical intervention has traditionally been recommended, but intrapericardial fibrinolysis could be an alternative.
