Intravenous leiomyomatosis with intracardiac extension: a report of two cases.

Uterine leiomyoma is a common disease in women; however, intravenous leiomyomatosis with intracaval and intracardiac complications is a rare condition. The initial presentation is dependent upon the severity of the intracardiac involvement. In this report, we describe two women with leiomyomatosis originating from the uterus and extending into the inferior vena cava to the right ventricle that was successfully resected using a two-stage approach.
