Author: V. Dimov, M.D.Reviewer: A. Aneja, M.D.Click here for thecase description and questions.The CT of the abdomen was significant for:1. Large abdominal aortic aneurysm (AAA).2. Diverticulosis.Abdominal aortic aneurysm (AAA) on the CT of the abdomen (click to enlarge the images).Abdominal aortic aneurysm (AAA) on the CT of the abdomen (click to enlarge the images).Diverticulosis on the CT of the abdomen (click to enlarge the images).Report of the CT of abdomen and pelvis with IV contrast:There is a large infrarenal distal abdominal aortic aneurysm (AAA), estimated to measure approximately 8.0 cm A.P. x 7.4 cm transversely. There is a large amount of mural thrombus, projecting posteriorly and to the right, in the proximal aneurysm, while being more circumferential in the distal aneurysm, which extends virtually to the level of the aortic bifurcation. The enhancing lumens directly abuts the anterior wall of the aneurysm proximally, but no definite aortic leak or evidence of retroperitoneal bleed is seen. Old aortic dissection is suspected. There is calcification at both renal artery ostia.GI tract was not well evaluated in the absence of oral contrast. There are fluid density lesions in both kidneys, likely representing bilateral renal cysts; these should be confirmed by ultrasound. No free air or free fluid is seen. There is severe degenerative change with associated spinal stenosis in the lumbar region.Pelvis: There is extensive sigmoid diverticulosis, without obvious CT c...
