Delayed presentation of a patient with a ruptured diaphragm complicated by gastric incarceration and perforation after apparently minor blunt trauma.

Rupture of the diaphragm is almost always due to major trauma and is most commonly associated with road-traffic accidents. We report a case of delayed presentation of a 35-year-old woman with a ruptured diaphragm, 11 days following apparent minor blunt trauma. This case illustrates how the diagnosis of ruptured diaphragm can be missed and demonstrates the importance of considering this diagnosis in all cases of blunt trauma to the trunk. It also demonstrates the potential pitfall of misinterpreting the chest radiograph, and the value of repeat imaging after insertion of a nasogastric tube.
