Intravenous leiomyomatosis extending into the right atrium.
Intravenous leiomyomatosis, also called benign leiomyoma, is a rare tumour that originates from a uterine myoma and spreads intravenously. A 54-year-old woman who had experienced faintness after a hysterectomy for uterine myoma 10 years earlier presented with this lesion. Ultrasonographic, computed tomographic and angiographic examination revealed a long tumour that originated in the uterus and extended into the right atrium through the right internal iliac vein and inferior vena cava. On the basis of a diagnosis of intravenous leiomyomatosis the neoplasm was extirpated by a one-stage cardiotomy and laparotomy with the aid of cardiopulmonary bypass. Retrospective histological analysis of the excised uterus revealed tumorous thrombosis in the venous cavity of the tunica muscularis. Some 26 cases in which open-heart surgery has been undertaken for intracardiac tumour thrombosis have been reported. These and the case described here are reviewed and analysed. In the present case, a full view of the tumour was obtained before surgery, and the lesion removed by a one-stage procedure using median sternotomy (cardiotomy) and laparotomy. Reports of one-stage procedures are few; only eight (30%) of 27 cases.
