Introduction: Cholecystocolonic fistula is usually a rare and late complication of gallstones and is the second most common cholecystoenteric fistula. Objective: To present the case of a cholecystocolonic fistula, a rare complication of cholelithiasis. Presentation of the case: A 50-year-old female patient who comes to our institution for recurrent abdominal pain. Discussion: Patients with FCC usually have a variable clinical presentation and are more often asymptomatic. When symptomatic, patients generally present with diarrhea, abdominal pain, jaundice, fever, nausea, vomiting, steatorrhea, and weight loss. The combination of pneumobilia, chronic diarrhea, and vitamin K malabsorption has been proposed as a pathognomonic triad for cholecystocolonic fistula. Conclusions: Cholecystocolonic fistula is a rare entity, radiologists should be aware of it and should be carefully informed if it occurs together with other hepatobiliary anomalies. The clinical triad pneumobilia, chronic diarrhea, and prolonged prothrombin time is seen in less than one third. Almost three quarters of the cases are asymptomatic and are diagnosed intraoperatively. Where cholecystectomy and repair of the colon wall is the most used treatment method.
