Strangulated diaphragmatic hernia presenting clinically as pericarditis

A case of strangulation of the transverse colon in a traumatic left diaphragmatic hernia manifesting as pericarditis is reported. This is unusual because pericardial signs in traumatic diaphragmatic hernia have been previously described in association with direct pericardial injury. This is the only such case where electrocardiographic changes of pericarditis were seen without direct pericardial trauma. The possibility of internal herniation through a traumatic diaphragmatic hernia must be considered in patients with chest symptoms and a compatible history.
