- We report two cases of common bile duct stone formed around a fish bone which migrated from the intestinal tract, along with their characteristic imaging findings. Two patients who had no history of previous operation were admitted because of cholangitis. Percutaneous transhepatic biliary drainage (PTBD) was performed and the cholangiogram showed filling defects with an unusually elongated shape in the common bile duct. After improvement of the cholangitic symptoms, the stones were removed through the PTBD tract under fluoroscopic guidance. A nidus consisting of a 1.5 cm sized fish bone was found in each stone removed.
