Draped aorta sign

The draped aorta sign is an important imaging feature that can be seen in contained rupture of an abdominal aortic aneurysm. It is highly indicative of aortic wall deficiency. 

This sign is considered present when the posterior wall of an aortic aneurysm drapes or moulds to the anterior surface of the vertebra. Usually, the fat planes between the aneurysm and vertebra are lost 1-3

Chronic contained rupture of an abdominal aortic aneurysm may cause vertebral erosions in up to 30% of cases 4,5.
