An isolated aneurysm of the thigh anterolateral branch of the greater saphenous vein in a young patient presenting as an inguinal hernia.

We report the first case of isolated aneurysm of the anterolateral branch of the greater saphenous vein in a 24-year-old man. The aneurysm was initially confused with an inguinal hernia. The patient referred with a respiratory distress due to a pulmonary embolism. The Doppler ultrasounds permitted to clarify the diagnosis. The aneurysm was removed en block under local anaesthesia. Surgeons should be aware to consider a venous aneurysm in the differential diagnosis of an inguinal mass. Indeed, due to its potential risk or embolism, the surgical treatment is mandatory.
