Strangulated traumatic diaphragmatic hernia simulating a subphrenic abscess.

Traumatic diaphragmatic hernias can be difficult to diagnose because of their varied clinical and radiologic signs and because patients may not present with symptoms for months to years following the injury. We report a case of a delayed presentation of a traumatic diaphragmatic rupture through which a portion of the stomach herniated and simulated a large subphrenic abscess.
