[A case of ascaridiosis of the common bile duct].

The authors present a case of ascariasis of the common bile duct in a 45 year old Portugese woman. Perfusion cholangiography showed a lacunar ribbon shaped image of the common bile duct and radiolucent gall-stones. The diagnosis of intracholedochal ascariasis was made and the patient operated: there was in fact an ascaris which was extracted by choledochotomy. Cholecystectomy. Straightforward aftermath.
