Identify two red flags associated with abdominal aortic aneurysm in patients with back or abdominal pain.

• A. Chronic back pain with no mass and stable vitals.
• B. Pulsatile abdominal mass and sudden, severe back or abdominal pain; syncope or hypotension.
• C. Gradual onset dull ache without systemic signs.
• D. Pain improves with rest.

Answer: (B)

When evaluating back or abdominal pain for a potential abdominal aortic aneurysm, the strongest warning signs are signs that rupture might be occurring. A pulsatile abdominal mass signals an enlarged aorta, and if it’s accompanied by sudden, severe back or abdominal pain with fainting or low blood pressure, that pattern points toward rupture with ongoing internal bleeding. This combination is what makes rupture risk clear and urgent. The other scenarios—chronic back pain with no detectable mass and stable vitals, a gradual dull ache without systemic signs, or pain that improves with rest—do not carry the same level of immediate concern for rupture. Rupture is a life-threatening emergency, so recognizing the abrupt severe pain plus hemodynamic instability with a pulsatile mass helps you identify the highest-risk situation quickly.
