Overview
Although CT scanning provides detailed anatomic information and is valuable in planning abdominal aortic aneurysm repair, it is not used as a screening tool because of the potential nephrotoxicity associated with the dye load, the cost, and the exposure to radiation.
Limitations of CT Scanning
The limitations include:
- Potential nephrotoxicity associated with the dye load
- Cost
- Exposure to radiation
- Suboptimal visualization of the origins of the aortic branch vessels
- Occasionally, inaccurate localization of the aneurysmal neck[1]

This patient presented with acute abdominal pain and hypotension. His non-contrast CT shows a large AAA and extensive periaortic haematoma. A thick (but subtle) hyperdense crescent is present within the aortic wall posteriorly and laterally which represents acute intramural hematoma, a sign of acute or impending rupture.
