- Abdominal tenderness
- A pulsating mass in the abdomen (in time with the heartbeat)
- Abdominal swelling

Tests are necessary to make the diagnosis of an abdominal aortic aneurysm.
Tests that may be used to evaluate an abdominal aortic aneurysm include:
Angiography is an imaging technique that may be used to evaluate the aorta. Dye is injected into the aorta, and an x-ray is used to show the flow of dye through the aorta. In someone with an abdominal aortic aneurysm, the dye shows an outline of an enlarged aorta.
AAA CT Scan
Abdominal CT scan provides information on the location and size of the abdominal aortic aneurysm.
Abdominal ultrasound is the most commonly used test to detect an abdominal aortic aneurysm.
