Spiral filling defect in the common bile duct

Abstract
A spiral filling defect in the common bile duct was found in an elderly woman with intermittent obstructive jaundice. A large, smooth papilla was shown on hypotonic duodenogram. At laparotomy, mucus strands were found in the DUCT, and ampullary carcinoma in the duodenum. The significance of the mucus strand and large duodenal papilla is discussed.
