Leiomyoma is a benign smooth muscle tumor that very rarely becomes cancer. Uterine leiomyoma or uterine fibroid is a benign tumor of uterus arising from smooth muscle cells of myometrium. Intravenous leiomyoma with intracardiac extension is a very rare clinical entity usually develops exclusively in women arising from either uterine venous wall or uterine leiomyoma  which is commonly misdiagnosed as primary cardiac tumor, such as Myxoma. We report the case of 48 year old woman with intravenous leiomyoma arising from left common iliac vein and extended to the heart through the inferior vena cava presented with symptoms of hemodynamic disorder. The patient had the history of uterine fibroid. Thoracoabdominal CT was performed to finalize the diagnosis. The intravenous tumor with its extension to the right atrium was ultimately resected via cardiotomy without the need of prolonged hypothermia during cardiopulmonary bypass.
