Mobile primary renal vein lipoma with an accelerated growth pattern

Abstract

Primary intravascular lipoma is a rare proliferation of adipose tissue originating from the wall of blood vessels. We have described an unusual case of a benign, but fast-growing, primary intravascular lipoma of the left renal vein with the mobile edge extending to the cavoatrial junction within just a few months. We have discussed the surgical indications, management, and technical considerations and highlighted the importance of surgical planning for similar cases.
