Intravenous Leiomyomatosis of Uterus

Abstract

We report a case with intravenous leiomyomatosis of uterus that showed characteristic appearances on MR. Magnetic resonance demonstrated a tangle of distended and folded tubular structures, well enhanced by Gd-diethylenetriamine pentaacetic acid. It was confirmed by surgery that these tubular structures reflected the vessels markedly dilated by intravascular tumor.
