Which finding is most suggestive of an asymptomatic abdominal aortic aneurysm?

• A. abdominal mass
• B. hypertension
• C. chest pain
• D. syncope

Answer: (A)

A pulsatile abdominal mass on physical examination is the most informative clue for an asymptomatic abdominal aortic aneurysm. When the abdominal aorta enlarges beyond its normal size, it can be felt or seen as a rhythmic, pulsating mass in the abdomen, especially in older adults or thinner individuals. This finding directly reflects dilation of the aorta, which is what an aneurysm is, and it can exist without other symptoms.

Hypertension is a common risk factor for aneurysm development but doesn’t by itself indicate an aneurysm on exam. Chest pain points to other problems such as cardiac ischemia or thoracic/aortic pathology higher up, not an isolated abdominal finding. Syncope is nonspecific and can arise from many different causes, not specifically an asymptomatic abdominal aortic aneurysm.
