title: [Leiomyosarcoma of the inferior vena cava].
abstract: The authors report a case of leiomyosarcoma of the infrarenal inferior vena cava presenting as an abdominal mass. CT and MR imaging and immunotyping led to the diagnosis of retroperitoneal leiomyosarcoma whose origin in the inferior vena cava was only confirmed by histological examination of the resection specimen. Surgical resection was followed by radiotherapy (4,500 rads) with a favourable course after 12 months. The progress in medical imaging and histology has considerably simplified the diagnosis of these rare retroperitoneal tumours. In the absence of any truly effective adjuvant therapy, treatment essentially consists of surgery and the clinical course is characterised by a high incidence of local recurrences.
