Figure 1

CT aortography. An 11.5 × 9 × 6 cm solid mass lying on the left side of the mid-abdominal aorta is shown. Contrast was seen extending to the level of the mass. Coeliac axis, superior mesenteric and renal arteries were filled but no opacification was present through the distal aorta and iliac arteries. Some contrast was seen in distal external iliac arteries, presumably arising from collateral vessels. Both kidneys did not enhance well, suggesting vascular compromise in both.
