[Value of x-ray computed tomography in abdominal aorta pathology].

Computed tomography allows positive diagnosis of aneurysms of all morphological types, and is invaluable for detection of possible extensions and complications and for follow up of both operated and non-operated cases. The CT scan also plays a crucial role for differential diagnosis of dissections, collateral artery aneurysms and tumoral lesions of the retroperitoneal space.
