Ruptured abdominal aortic aneurysm with aortocaval fistula and embolic IVC thrombus-a rare clinical scenario detected on CT angiography.

Rupture with fistulization of an abdominal aortic aneurysm with the vena cava is a rare complication and typically presents with congestive cardiac failure. Embolization of a thrombus from the aneurysm into the vena cava can however present in the absence of failure symptoms which can make it difficult to diagnose clinically without cross sectional imaging.
