A case report of fulminant primary streptococcal pericarditis

Background Bacterial pericarditis is a rare, rapidly progressive, and highly fatal infection, even with drainage and antibiotics. Gram-positive cocci, specifically Streptococcus pneumoniae, have been the most common cause of bacterial pericarditis from either haematogenous dissemination, or spread from another adjacent site of infection. Following the introduction of antibiotics in the 1940s and more recently the pneumococcal conjugate vaccine, the incidence has drastically decreased. Case summary A previously healthy young male was diagnosed with acute pericarditis with no signs of haemodynamic compromise on initial presentation. Several hours later, he became unstable suffering from cardiac tamponade and septic shock. Despite urgent pericardiocentesis and drainage of purulent fluid, culture positive for streptococcus pneumoniae, multi-organ failure was eventually fatal. Discussion We describe a rare case of primary S. pneumoniae purulent pericarditis leading to tamponade, septic shock, and death. Due to the high mortality rate of purulent pericarditis, a high index of suspicion is needed in order to initiate appropriate therapy with antibiotics and drainage.
