[Leiomyosarcoma of the inferior vena cava. Review of the literature apropos of a case].

The authors report a case of leiomyosarcoma (LMS) of the second segment of the inferior vena (IVC) with liver metastasis. Treatment by surgery and chemotherapy proved to be effective, as the patient is asymptomatic 8 years after the first operation. A review of the literature shows that these tumours are rare and have a slow course. The symptoms are often relatively minor and depend on the caval segment involved. The best examination for positive and topographic diagnosis remains computed tomography, but MR Imaging is promising. The prognosis remains severe (mean survival: 2 years) and surgery is the main treatment, with various techniques according to the caval segment involved.
