Duodenocaval Fistula in a Patient with Inferior Vena Cava Leiomyosarcoma Treated by Surgical Resection and Caval Polytetrafluoroethylene Prosthesis

Figure 1

Plain abdominal radiography, performed at the time of emergency admission, shows the presence of a gastroduodenal air-fluid level (white arrow). The partial opacification of residual intestinal lumen (arrowheads) is due to assumption of oral contrast agent in a previous radiographic study performed one week before in another institution.
