Abstract

Lipomas are common soft tissue tumors that are located in the body tissues containing adipose tissues. However, lipomas arising from the walls of a vein are very rare. Intravascular lipomas have been described most commonly in association with the inferior vena cava. Intravascualar lipomas involving the subclavian vein are rare. We are reporting a case of an asymptomatic lipoma of the right subclavian vein, growing into the right brachiocephalic vein.
