The radiograph has several findings. First, there are multiple fractures along the left lateral ribs. Second, there is a small left apical pneumothorax. Most significant, though, is an elevated left hemidiaphragm. There appears to be stomach or possibly bowel protruding into it.
Although a large hiatal hernia could yield similar findings, in the setting of trauma, one must be concerned about a traumatic diaphragmatic hernia. Subsequent CT of the chest, abdomen, and pelvis confirmed a defect within the diaphragm, with a significant portion of the stomach herniating into the left chest.
Surgical consultation was obtained. The patient was admitted and ultimately underwent surgical intervention to repair the problem.
