Primary aorto enteric fistula a rare but life threatening condition: a case report.

Primary aorto enteric fistula is a very rare but life threatening condition. We report a case of primary aorto enteric fistula in a 62-year-old man whose diagnosis was only made at laparotomy. A high index of suspicion along with a good history and physical exam is critical for making a successful diagnosis. Surgical exploration is warranted if other investigation is not conclusive.
