Question
19 year-old male s/p high-speed MVC with hypotension and diminished breath sounds on left. Diagnosis?
Answer
Answer: Diaphragmatic rupture (Note position of NG tube on image below).
·Uncommon; less than 1% of all traumatic injuries
·Diagnosis may be obvious on CXR (as in example) or subtle (e.g., diaphragmatic elevation, basilar atelectasis, etc.)
·Requires a high-index of suspicion because delayed diagnosis increases the risk of abdominal organ herniation or strangulation.
·Mortality depends on the mechanism and presence of associated injuries; mortality is highest for blunt injuries.
