title: Pelvic leiomyomatosis with intracaval and intracardiac extension: a case report and review of the literature.
abstract: BACKGROUND
  Intravenous leiomyomatosis with intracaval and intracardiac extension has been rarely described in surgical, gynecological, and radiological literatures. Complete excision of the tumor is essential for a favorable outcome. Because of the uniqueness of this tumor having an absent or localized attachment site, its removal is feasible when assisted, prior to surgery, with appropriate imaging and planning.
  
  
  METHODS
  The case was a 46-year-old woman, with intravenous leiomyomatosis originating from the uterus and extending to the inferior vena cava and right atrium, with extensive intracaval attachment, diagnosed from the various preoperative studies and operated successfully through the single-stage approach using cardiopulmonary bypass.
  
  
  CONCLUSIONS
  We present an unusual case of intravenous leiomyomatosis originating from the uterus and extending to the inferior vena cava and right atrium with extensive intracaval attachment. We include a brief review of the literatures.
