Clinical Presentation

The patient is a 50-year-old who underwent repair of an abdominal aortic aneurysm (AAA).

Case images: Frontal and lateral three-dimensional (3D) volume-rendered computed tomographic angiograms (CTAs) show a large infrarenal AAA extending to the iliac bifurcation. The axial source image most accurately reflects the true diameter of 8 cm. Frontal and lateral 3D volume-rendered CTAs show interval placement of an aortic endograft.

Axial image shows contrast leakage (arrow) into the anterior aneurysm sac at the level of the inferior mesenteric artery.

Differential Diagnosis

• Type 2 endoleak
