Preoperative intravascular ultrasonographic evaluation of leiomyosarcoma of the inferior vena cava: A case report

Abstract

Leiomyosarcoma of the inferior vena cava is a rare malignant tumor originating from smooth muscle cells of the vascular media. Its preoperative diagnosis by conventional noninvasive examinations such as abdominal ultrasonography, X-ray computed tomography, and magnetic resonance imaging, may be difficult because of their nonspecific findings. We present the case of a 72-year-old woman with leiomyosarcoma of the inferior vena cava diagnosed by intravascular ultrasonography.

Keywords: inferior vena cava; intravascular ultrasonography; leiomyosarcoma; preoperative.
