CTICasesRuptured thoracoabdominal aortic aneurysm
Imaging findings
CT angiogram shows a large hemothorax and a ruptured thoracoabdominal aortic aneurysm with active contrast extravasation, accompanied by extensive calcification extending from the thoracic aorta into the iliac arteries.
Key takeaways
Active extravasation of contrast into the pleural space on CTA is diagnostic of acute aortic rupture. In young patients, this can be secondary to vasculitis, drug abuse, or infection, and carries a high mortality rate.
