We describe the case of a 68-year old woman who presented with an acute onset of epigastric pain, nausea and vomiting that had begun 12 hours earlier. Acute pancreatitis was diagnosed based on the elevated value of serum amylase. Triglycerides, calcium, liver enzymes and bilirubin values were within normal limits. The patient denied having consumed alcohol. An abdominal ultrasonography showed gallstones and sludge in the gall bladder. As part of the preoperative evaluation, the patient underwent MRCP. The following anomalies were diagnosed: pancreas divisum, drainage of the cystic duct into the right hepatic duct near the hepatic hilum and drainage of the right median segmental hepatic duct into the left hepatic duct. The patient was referred to a tertiary hospital for further evaluation and treatment where she underwent laparoscopic cholecystectomy. The postoperative course was uneventful and the patient was discharged three days later. During the 4-month follow-up period the patient remained asymptomatic.
