Intravenous leiomyomatosis is a histologically benign smooth-muscle tumor arising from either a uterine myoma or the walls of a uterine vessel with extension into veins. We describe echocardiographic features of intravenous leiomyomatosis with spread into the right-sideacardiac chambers. The patient was a middle-aged woman, with prior history of hysterectomy 2 years earlier who presented with cardiac symptoms and signs. Echocardiographic features included: 1) elongated mobile mass extending from the inferior vena cava, and 2) multiple masses in the right-heart chambers (right atrium and ventricle).
Intracardiac leiomyomatosis should be considered in a female patient presenting with an extensive mass in the right-sided cardiac chambers.
