Intravenous leiomyomatosis extending into the right ventricle: one-stage radical excision during hypothermic...

A case of intravenous leiomyomatosis with extension into the right ventricle is described. A tumor in the inferior vena cava was detected 5 years after a hysterectomy had been performed for a myomatous uterus, but was misdiagnosed as an intracaval thrombus. Three years later this tumor was discovered after it had enlarged and intruded into the right ventricle. The correct diagnosis was made after a complete evaluation. The patient underwent surgery employing simultaneous sternotomy and laparotomy. Radical excision was achieved using cardiopulmonary bypass with hypothermic circulatory arrest. The diagnostic and surgical approaches are reviewed and discussed.
