Which symptom is indicative of an aortic aneurysm?

A pulsatile abdominal mass is a classic symptom of an aortic aneurysm, particularly when it involves the abdominal aorta, known as an abdominal aortic aneurysm (AAA). As the aneurysm enlarges, the weakened section of the wall of the aorta may become palpable as a mass, which can be felt pulsating with the heartbeat. This finding is critical in clinical practice because it can indicate the presence of an aneurysm that may be at risk of rupture, which is a medical emergency.

Localized pain can occur with an aortic aneurysm, but it is often vague and may not be specific to the aneurysm itself. Chest tightness, although it may be associated with other cardiovascular concerns, is not directly indicative of an aortic aneurysm specifically. Nausea is a nonspecific symptom that can arise from many different conditions and does not provide clear diagnostic insight into an aortic aneurysm. Thus, the presence of a pulsatile abdominal mass stands out as the most definitive and concerning indicator for an aortic aneurysm, warranting further investigation and management.
