A case of cholecystoduodenal fistula and duodenal ileus diagnosed by magnetic resonance imaging (MRI) preoperatively is reported herein. A 91-year-old man with vomit was referred to our institute. Abdominal computed tomography revealed pneumobilia and distended proximal duodenum with an impacted gallstone. MRI showed a cholecystoduodenal fistula as well as an intense inflammatory response around the hepatoduodenal ligament. The gallstone was simply removed through an enterotomy without cholecystectomy because of patient's condition and severe adhesion to the surrounded organs. Diagnosis of enterobiliary fistula by MRI is easy and helpful for decision make for a safer surgical approach.
