Tension hydropneumothorax as delayed presentation of traumatic rupture of the diaphragm.

Diaphragmatic rupture due to blunt trauma is well recognised though uncommon. Most cases are diagnosed at the time of injury, but a proportion remain undiagnosed, only to present some months or even years later. This "delayed" group can present in a number of ways, including chronic abdominal and chest problems or an acute crisis. Herniation of abdominal viscera is the most common sequel, with strangulation and gangrene as the most serious complication. This paper reports a case of delayed presentation of diaphragmatic rupture and herniation presenting as tension hydropneumothorax due to small bowel perforation. A short discussion addresses the problems in diagnosis of this condition. We believe this to be the first reported case of perforated small bowel leading to tension hydropneumothorax.
