Kim YH, Kim YJ, Park WK, Lee SK, Kwon JH, Woo SK - Korean J Radiol (2004 Jul-Sep)

Bottom Line: 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.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.

ABSTRACT
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.

Mentions: A 67-year-old man who had no previous history of abdominal surgery was admitted to our institution because of epigastric pain and fever. Serum bilirubin was 10 mg%, and was mostly conjugated. CT showed mild dilatation of the intra- and extra-hepatic ducts, but there was no demonstrable obstructive cause. US demonstrated the presence of a CBD stone. PTC showed an elongated filling defect in the CBD (Fig. 2A). After improvement of the cholangitic symptoms, stone removal was performed through a PTBD tract under fluoroscopic guidance. A 1.5 cm sized nidus consisting of fish bone was found in the removed stone (Fig. 2B).
