Isolated common femoral artery aneurysm: a case report.

Introduction: Isolated aneurysm of common femoral artery is a rare occurrence. They may mimic other common conditions like groin lymph nodes or groin hernia.

Case Presentation: Here we present a case of 61-years-old Chinese gentleman who presented with a right groin lump, which was suspected to be groin hernia but turned out common femoral artery aneurysm. The aneurysm was surgically excised and a prosthetic vascular repair was done.

Conclusion: Isolated common femoral artery aneurysms are rare and can mimic groin hernias, so one must be careful. Color Doppler is the investigation of choice. Best treatment modality is surgical excision with repair with or without graft for aneurysms > 2.5 cm.
