Introduction: True femoral aneurysms are a rare but important cause of groin swelling. Report: We report a 79 year-old male, presenting with intermittent claudication and leg oedema after 25 years of a growing left groin swelling. On examination the mass was 14.5 cm in diameter and pulsatile with an audible bruit. Distal pulses were absent. Perfusion was restored by interposition of a PTFE graft between CFA and PFA. Discussion: This case presents the largest reported true common femoral aneurysm. Conventional open repair is recommended when diameter exceeds 2.5 cm. Although endovascular techniques are evolving, they were not possible in this case. “Bill's Bulge” – a 14.5 cm Femoral Aneurysm Case Report and Literature ReviewEJVES ExtraVol. 19Issue 1PreviewTrue femoral aneurysms are a rare but important cause of groin swelling.
