The scout view shows a mid-abdominal mass displacing the digestive structures.

The CT images with sagittal and coronal reconstruction demonstrate a large abdominal aneurysm of the infrarenal segment with circumferential mural thrombosis, measuring 9 cm in the anteroposterior diameter, 11 cm in transverse diameter, and 17 cm in length. The common iliac arteries are also dilated.

Note multiple simple hepatic and renal cysts as well as small lipoma at the ileocecal junction.
