A Soft, nonpulsatile, reducible inguinal bulging in the left inguinal area; B color Doppler sonography of the left lower extremity venous system revealed incompetency of the left-sided saphenofemoral junction and a large venous aneurysm originating from the left-sided saphenofemoral junction; C histopathology section of the aneurysmal lesion demonstrating dilated uniloculated mass with endothelial lining, indicative of tunica intima (arrowhead) (×100 hematoxylin and eosin stain); D the lesion’s wall cut section demonstrating thickening of the three layers of the venous histology with destruction of tunica media and its replacement by loose connective tissue with mild myxoid degeneration (×400, hematoxylin and eosin stain)
