Primary Venous Aneurysm of the Basilic Vein at the Distal Forearm

Venous aneurysm (VA) is an uncommon solitary focal dilation of a vein. Primary superficial VA, which may be associated with congenital weakness of the vein wall, is rare. In this case study, an extremely rare primary superficial VA from the basilic vein in the distal forearm is reported. The patient presented with a painless soft mass in the ulnar aspect of the distal forearm without any history of trauma, inflammation, or systematic disease. The mass was prominent with the arm in dependence and diminished with the arm elevated. Ultrasound scanning revealed a saccular dilation of the vein coursed along the path of the basilic vein. Pulsed-wave Doppler confirmed the venous origin. No thrombus was found inside the VA. The patient was recommended to observe the change with no need for surgery at the time by the vascular surgeon.
