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

Figure 2

Transverse abdominal unenhanced CT scan acquired after oral administration of a water-soluble contrast agent. The images show the collapse of the second part of the duodenum (white arrow (a)) and the presence of an air bubble collection (open arrow (b) and (c)) (35 × 35 × 15 mm), located between the posterior wall of the duodenum and the collapsed IVC graft. The transaxial CT images of the lower tract of the duodenum demonstrate the trouble of assessing attenuation differences between IVC graft and luminal contrast agent (arrowheads (d)).
