Two Case Reports of Intravenous-Cardiac Leiomyomatosis.

Intravenous-cardiac leiomyomatosis is an uncommon tumor arising from invasive uterine leiomyomata, with nodular masses extending into the inferior vena cava, right heart chamber, and even pulmonary arteries or lung. This report describes two cases of intravenous leiomyomatosis invading the right heart. A total hysterectomy with bilateral salpingo-oophorectomy and intravenous leiomyomata was performed. However, the intracardiac tumor was pulled apart, and the residual tumor remained unchanged at the 4-year follow-up in one patient. Its early diagnosis might be difficult because cardiac symptoms only develop once the tumor extends into the right heart or pulmonary arteries, resulting in cardiac insufficiency. The treatment depends on radical resection of pelvic and intravenous leiomyomatosis and bilateral salpingo-oophorectomy. [ABSTRACT FROM AUTHOR]
