Abstract
We report a case of intravenous leiomyomatosis extending to the inferior vena cava. The patient was a 74-year-old woman, who had a history of total hysterectomy due to uterine leiomyoma about 30 years previously and upper lobectomy of the right lung due to lung cancer about 7 months before. Computed tomographic scan showed that an intravenous tumor extended from the right internal iliac vein to the inferior vena cava. We resected the intravenous tumor which was shown to be a leiomyoma, positive for estrogen receptor.
