Acquired Bile Duct Blockage: Entry of Hepatobiliary Agent Into an Intrahepatic Abscess

A 70-year-old man had a 23-year history of gallstones, pancreatitis, and necrotizing cholangitis. Although a biliary stent had been placed, many hospital admissions were required. He was examined for epigastric pain, icterus, and fever. A hepatobiliary study revealed little drainage of radiotracer from the liver. A superior pole hepatic defect, revealed on delayed images, was responsible for entry of the hepatobiliary radiotracer. Drainage of the region revealed an intrahepatic abscess.
