Primary Aneurysm of Basilic Vein, A Rare Case Report

Abstract

When compared to arterial system, the venous aneurysm is a rare entity. Venous aneurysm (VA) is an uncommon solitary focal dilation of a vein and it could be primary or secondary. Primary superficial VA is rare, which may be associated with congenital weakness of the vein. In this case study, an extremely rare primary superficial VA of the basilic vein in the forearm is reported. A young girl presented with a painless soft mass in the ulnar aspect of the upper left forearm without any history of trauma, inflammation, or systematic disease. The mass was prominent with the arm in dependence and diminished when the arm elevated. Ultrasound scanning revealed a well-defined anechoic cystic structure along the path of the basilic vein with no arterial flow. Pulsed-wave Doppler confirmed the venous origin. The patient was advised to observe for the change with no need for surgery or any intervention at the time.
