A 4 cm diameter rounded collection of fluid superiorly adjacent to the sigmoid colon which contains many diverticulae and is thick walled. It is in close proximity to the bladder wall, which also appears thickened. No gas can be seen in the bladder lumen to suggest a colovesical fistula.
In addition the aorta is aneurysmal with extensive irregular mural thrombus and extensive vascular calcification seen along the entire arterial tree. The right common femoral artery is also aneurysmal with evidence of previous intervention in the region.
Incidental renal cysts and splenunculus noted. Extensive calcified pleural plaques are also noted, presumably representing prior asbestos exposure.
