Non Traumatic Neuroma of the Bile Duct: Report of a Case.

We report a case of a 46-year-old man with a stricture of the bile duct which was caused by neuroma. The patient had a history of six months jaundice without a previous history of abdominal surgical operation. MR imaging and MRCP clearly picked up the dilatation of intrahepatic biliary ducts and the level of stenosis, but it was very difficult to differentiate benign neuroma from malignant stenosis of the common bile duct. Results of preoperative CT, MRI and ERCP evaluation and postoperative histological examination were presented.
