projecting outside the anterior and lateral walls
of the abdominal aorta. Hyperdense structures

FIG. 12.14 Inlammatory Abdominal Aortic Aneurysm (AAA) Before and After Treatment. (A) Computed tomography (CT) scan of inlammatory
AAA, which has maximal diameter of 4.9 cm. Note calciication (white arrow) indicating the aortic wall. Inlammatory tissue is present
outside the aorta (red arrows). Patient was symptomatic and was treated with an endoluminal graft shortly after this scan. (B) CT scan 2 years
later shows that aortic size is smaller. Inlammatory mass has disappeared.
