Retroperitoneal leiomyosarcoma infiltrating the inferior vena cava (IVC)--a case report.

ABSTRACT

Retroperitoneal soft tissue sarcomas are difficult to treat because the retroperitoneal organs and great vessels are often involved by the time the patients come to a surgeon. We present the case of a 48 year old woman with a retroperitoneal leiomyosarcoma that had infiltrated the IVC and the renal veins.
