Massive intrapericardial herniation of stomach following pericardial window.

Herniation of intra-abdominal contents into the pericardial cavity is rare. We describe one such case occurring after creation of a 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.
