Blunt traumatic abdominal aortic rupture: CT imaging.

Blunt abdominal aortic trauma is a rare but potentially lethal event. It is commonly associated with high-speed motor vehicle accidents. Intimal flap, thrombosis, and pseudoaneurysm of the abdominal aorta are the more common findings. We present a case of blunt abdominal aortic trauma in which CT disclosed free aortic rupture with intraabdominal bleeding and a huge retroperitoneal hematoma, an extremely rare finding among patients reaching the hospital alive, due to its high and immediate mortality rate.
