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

Figure 3

Follow-up contrast-enhanced MDCT study performed three months later. Axial ((a) and (b)) and coronal (c) CT images well show the presence of a fluid-filled fistula (white arrows (a) and (c)) between the duodenum and the IVC graft and an air bubble collection inside the prosthesis (open arrows (b) and (c)). Axial (a) and sagittal (d) CT images better show the path of enteric fluid into the IVC graft. Dilatation of the stomach with an air-fluid level and thickening of the duodenum are also evident.
