title: Intravenous leiomyomatosis of the uterus with continuous extension into the pulmonary artery.
abstract: A 56-year-old woman presented with an intracardiac tumor, as shown by two-dimensional echocardiography. Surgical treatment, undertaken in two stages, revealed a tumor which arose in the uterus, passed through both ovarian veins, the inferior vena cava, the right atrium and ventricle, and the pulmonary trunk, and extended to both pulmonary arteries. The upper portion of the tumor was removed in the first surgical operation, and the remaining tumor was removed during a second operation 1 year later. Both specimens were identical in appearance, and a pathohistological diagnosis of benign leiomyoma was made.
