Intrapericardial Diaphragmatic Hernia Associated With Cardiac Tamponade

Herniation of intra-abdominal contents into the pericardial cavity is rare. We observed a delayed intrapericardial diaphragmatic hernia presenting as a tamponade secondary to a previous pericardioperitoneal window for drainage of a pericardial effusion. The diagnosis of an intrapericardial hernia should be considered in patients presenting with gastrointestinal and/or cardiorespiratory symptoms following surgical procedures involving the diaphragm.
