Pulsating abdominal mass in middle-aged men with tearing pain radiating to the back most suggests which condition?

• A. Aortic dissection
• B. Renal colic
• C. Hernia
• D. Abdominal Aortic Aneurysm

Answer: (D)

The key idea here is recognizing an abdominal aortic aneurysm. When a middle‑aged man presents with a pulsatile abdominal mass accompanied by back or tearing‑like pain, the pulsatile mass points strongly to an aneurysm of the abdominal aorta rather than a simple abdominal pain source. An aneurysm can cause back or abdominal pain as it stretches or leaks, and the presence of a palpable, rhythmic abdominal pulse that can be felt through the abdominal wall is a classic clue.

In contrast, renal colic causes intense flank or groin pain that comes in waves and typically doesn’t create a pulsatile abdominal mass. A hernia presents as a bulge in the groin or abdomen that may protrude with straining but isn’t usually pulsatile and isn’t described as a tearing pain radiating to the back. Aortic dissection causes sudden, severe tearing chest or back pain and may include differences in blood pressure between limbs and other signs, but the identifying pulsatile abdominal mass is more characteristic of an abdominal aortic aneurysm.

Because an AAA can rupture and become life‑threatening, this presentation warrants urgent imaging and vascular assessment, with close hemodynamic monitoring and rapid consultation for definitive management.
