Back pain with which finding signals possible abdominal aortic aneurysm requiring immediate attention?

• A. Back pain with fever
• B. Pulsatile abdominal mass
• C. Visceral tenderness
• D. None of the above

Answer: (B)

A pulsatile abdominal mass is the most concerning finding here because it directly points to an abdominal aortic aneurysm. In an older patient with back pain, discovering a pulse-like fullness in the abdomen suggests the aorta is dilated and at risk of rupture, which is a medical emergency. Immediate action is needed: confirm with imaging (bedside ultrasound if unstable, CT angiography if stable), stabilize the patient, and involve vascular surgery urgently. Back pain with fever would lean toward infection (such as an infected aneurysm or other intra-abdominal process) rather than a straightforward aneurysm signal. Visceral tenderness localizes to specific organs and doesn’t specifically indicate AAA. Therefore, the pulsatile abdominal mass best signals the need for rapid attention.
