Abdominal Aortic Aneurysm. A. In this 68 year old man, a lateral radiograph reveals severe atherosclerotic plaques depicted as conduit wall calcification outlining a 9 cm diameter aneurysm (arrows) extending from the upper abdominal aorta to the iliac arteries near the lumbosacral junction. B. In another patient, observe the metallic mesh of an aortic and iliac artery graft. This patient also has skeletal metastasis with osteoblastic lesions within the L2 and L5 vertebral bodies. C. A longitudinal diagnostic ultrasound image through the center of an aneurysm (same patient as in A) documents that the diameter of the lumen at its maximum width is 9.84 cm.
