title: Surgical clip as a nidus for a common bile duct stone: radiographic demonstration.
abstract: Surgical clips can migrate into the biliary tract and act as a nidus for stone formation. We present a case of a surgical clip within a common bile duct stone. This diagnosis was suggested by clip movement on serial abdominal radiographs and metallic density within the common duct stone on computed tomography. Confirmation was made by retrograde cholangiogram.
