Intravenous Leiomyomatosis with Right Atrial Involvement

Intravenous Ieiomyomatosis is considered to be a rare neoplastic disease usually arising from uterine myomata. Mortality from this condition is usually the result of intracardiac involvement. The case of a 42-year-old woman is reported who had undergone hysterectomy for uterine myoma and in whom intravenous leiomyomatosis extended into the inferior vena cava and right atrium. The histologically benign tumor was excised from the right atrium and suprahepatic portion of the inferior vena cava. Though at the subsequent laparotomy the tumor invading the infrarenal inferior vena cava and the right common iliac vein could not be completely extirpated because of adhesions, the patient was asymptomatic at 14 months of follow-up.
