A Case of Intravenous Leiomyomatosis / 대한산부인과학회지

Intravenous leiomyomatosis (IVL) is rare and it is characterized by intravascular nodular masses of histologically benign smooth muscle that may extend along the inferior vena cava or reaching the right-sided cardiac chamber, and eventually the lung. Although histologically benign, IVL might be malignant in its mode of behavior. We report a case of IVL that grew in a vessel of myometrium of uteri.
