title: Delayed traumatic diaphragmatic hernia simulating acute tension pneumothorax.
abstract: The diagnosis of acute diaphragmatic injury is difficult to establish in the immediate posttraumatic period. Patients with delayed diaphragmatic herniation frequently present months to years after the initial injury with manifestations of visceral incarceration, obstruction, ischemia from strangulation, or perforation. Patients with diaphragmatic herniation presenting with clinical tension pneumothorax are rare. We describe the case of a 23-year-old female who 16 weeks following a stab wound to the low chest presented with this clinical picture caused by herniation of abdominal viscera into the chest. A review of this entity and methods of discovery of delayed traumatic diaphragmatic herniation are described.
