Occult pseudoaneurysm of the abdominal aorta following gunshot wound: the importance of plain film findings.

Early abdominal x-ray film and appreciation of paraspinal bullet fragments could have led to its earlier detection. A portable abdominal x-ray film should be a routine part of the preoperative resuscitation of abdominal gunshot wounds.
