Local recurrence of renal cell carcinoma causing duodenal-inferior vena caval fistula: case report and review of the literature.

We report the first case of a duodenal-inferior vena caval (IVC) fistula resulting from locally recurrent renal cell carcinoma (RCC). A 45-year-old man presented with gross hematuria and underwent a right radical nephrectomy to treat a solid renal mass. Histologic evaluation showed RCC, Stage pT3aN0M0. The patient presented 21 months later in hemorrhagic shock, with upper gastrointestinal bleeding. He underwent an exploratory laparotomy and Whipple procedure for a mass in the second portion of the duodenum extending to the inferior vena cava with a secondary duodenal-IVC fistula. We describe this case and review the previously published reports of duodenal-IVC fistulae.
