A case report of intravenous leiomyomatosis extending into the heart.

The patient was a 47-year-old woman who underwent total hysterectomy for uterine leiomyoma in 1994. Two years later, intracaval and intravenous tumors were found by ultrasonic cardiography, magnetic resonance imaging, enhanced chest computed tomography, and venography. The patient underwent total removal of these tumors. Pathological findings indicated that these tumors were leiomyomas. After comparing the present findings with those of similar cases in the literature, we concluded that our patient had intravenous leiomyomatosis extending into the heart.
