Great saphenous vein aneurysm mimicking inguinal hernia: a case report

Diagnosis of venous aneurysm may be difficult and can be misjudged as mass-like lesions, including hernias. Here we present the case of a patient with a great saphenous vein aneurysm misdiagnosed and operated as an inguinal hernia.

A 39-year-old Middle Eastern/Persian male presented with left inguinal bulging 15 years ago, which was misdiagnosed and operated on with a diagnosis of inguinal hernia. He was referred to our clinic, in which color Doppler sonography revealed left-sided saphenofemoral junction incompetence with severe flow reversal during the Valsalva maneuver, in favor of a great saphenous vein aneurysm. Ligation of left saphenofemoral junction and stripping of saphenous vein, and stab avulsion phlebotomy of left lower extremity varicose veins, were done. He was discharged the next day after the operation with an uneventful postoperative course or complication on follow-up.

Venous aneurysms can be misdiagnosed as other, more common, mass-like lesions, such as inguinal hernias. Therefore, our report emphasizes the consideration of thorough assessment and utilization of color duplex sonography to prevent further misdiagnosis and unnecessary intervention and operations.
