Traumatic, pericardio-diaphragmatic rupture: an extremely rare cause of pericarditis

A 54-year-old man with a recent history of blunt abdominal trauma presented to the Emergency Department with severe pain in the chest and abdomen. He was tachycardic, tacypneic, and hypoxic. An electrocardiogram (EKG) at that time showed ST elevation and PR depression consistent with acute pericarditis, and a computed tomography (CT) scan subsequently showed herniation of abdominal contents into the pericardium and left hemithorax. After surgical repair of the diaphragmatic defect and intrapericardial hernia, the EKG findings resolved. He recovered over the course of several weeks and was subsequently discharged home.
