When you examine a groin swelling thought to be a hernia, which finding should most strongly prompt you to consider a vascular cause?
- A A visible cough impulse over the swelling You picked ✕
- B Tenderness and warmth over the swelling You picked ✕
- C No bowel sounds over the swelling You picked ✕
- D A swelling that transilluminates You picked ✕
- E A bruit over the swelling You picked ✓
Correct!
Incorrect
The answer is E: A bruit over the swelling
Explanation
Why E is correct
See Auscultation and Transillumination. Option E is correct. A bruit (pronounced "brooee") is a swooshing or whooshing sound heard through the stethoscope over a blood vessel, and it tells you that blood is flowing turbulently there. A groin swelling that makes this sound, or that pulsates strongly, should make you think of a femoral artery aneurysm (a ballooning of the main artery of the leg where it passes through the groin) rather than a hernia, which is a loop of bowel or omentum pushing through a weak point in the abdominal wall. The mistake is easy to make, because a femoral aneurysm can present as a groin bulge and be confused with a hernia. It matters because aneurysms can clot, shed small clots downstream (emboli) or rupture, so a suspected one needs a vascular assessment of the leg circulation instead of a routine hernia pathway.
- Bruit: a whooshing sound over a vessel from turbulent blood flow.
- Groin swelling: one that pulsates or has a bruit suggests a femoral artery aneurysm, not a hernia.
- Action: needs a vascular assessment because aneurysms can clot, embolise or rupture.
Why the other options are incorrect
- A. A visible cough impulse over the swelling: A cough impulse is a classic sign of a hernia, not of an arterial lesion. It shows that a rise in abdominal pressure forces bowel or omentum through a defect, whereas a bruit points to turbulent arterial flow. Your answer
- B. Tenderness and warmth over the swelling: Tenderness and warmth suggest inflammation or a strangulated hernia, not an aneurysm. They are not the typical clue to turbulent arterial flow. Your answer
- C. No bowel sounds over the swelling: A silent swelling can still be a hernia, because omentum makes no sound and bowel inside a hernia may be quiet. Absent bowel sounds do not point to turbulent arterial flow. Your answer
- D. A swelling that transilluminates: Transillumination suggests a fluid-filled scrotal swelling such as a hydrocoele, not an arterial cause in the groin. It does not produce a bruit or pulsation. Your answer

A patient has intermittent right groin swelling. Lying flat, no lump is visible. There is a faint scar in the right groin from previous surgery, and the left groin looks normal at rest. Which inspection strategy is most likely to detect a groin hernia?
-
2
You examine a right groin swelling that lies below and lateral to the pubic tubercle. It is tender, it is irreducible and the overlying skin is red. The patient also reports vomiting and absolute constipation. After letting the patient dress, restoring their dignity, thanking them and washing your hands, which closing statement is most appropriate?
