Pseudoaneurysm and ilio-caval fistula caused by malignant fibrous histiocytoma of the aorta--CT diagnosis and angiographic confirmation

We report a case of a malignant fibrous histiocytoma (MFH) of the aortic bifurcation, which manifested as a pseudoaneurysm with the formation of an ilio-caval fistula, a complication about which, to our knowledge, nothing has been published previously. Spiral CT, catheter arteriography and venography were complementary in the diagnostic procedure.
