Arteriomegaly and aneurysmal disease

The predisposition to multicentric aneurysmal disease in the aorta and peripheral arteries suggests a diagnosis of arteriomegaly. The CT scan through the lower abdomen (A) shows an abdominal aortic aneurysm (AAA) (arrow). In the pelvis (B), aneurysms of the common iliac arteries can be seen, larger on the right (arrow) than the left. In the lower extremities (C and D), ectatic femoral arteries (bilateral arrows, C), and bilateral popliteal aneurysms (bilateral arrows, D) are seen. The right popliteal aneurysm is lobulated (arrowhead).
