[Pericardial empyema as a rare complication of pneumococcal pneumonia]

The case histories of 3 patients hospitalised for severe pneumococcal pneumonia are reported. Electrocardiography showed generalized ST-segment elevations and echocardiography revealed pericardial effusion. Pericardiocentesis was performed and analysis of the punctate fluid was consistent with empyema. The pericardial empyema was removed by percutaneous drainage in one patient and by thoracoscopy in 2. During the course of the disease, 2 patients developed constrictive pericarditis after 4 to 6 weeks, necessitating epi- and pericardectomy in one. When patients with pleuropneumonia present generalised ST-segment elevations in the ECG, the possibility of pericardial involvement should be evaluated by echocardiography. The pericardial empyema must be removed as soon as possible, ideally by thoracoscopic drainage. Percutaneous drainage often fails to evacuate the empyema completely and does not prevent recurrent effusions. Constrictive pericarditis occurs early in the course of the disease and is a serious complication. When a patient suffering from constrictive pericarditis remains symptomatic despite optimal conservative therapy, pericardectomy should be performed. However, as only one of our three patients required the procedure, it should not be routinely performed.
