3. • Fig GI 44-1 Choledochal cyst. Cholangiographic
contrast material fills the huge fusiform
dilatation of the common bile duct and the
markedly dilated intrahepatic ducts.

4. • Fig GI 44-2 Choledochocele. (A) A well-defined, smooth
filling defect (arrow) projects into the duodenal lumen on
an upper gastrointestinal series. (B) At cholangiography, the
bulbous terminal portion of the common bile duct fills with
contrast material and projects into the duodenal lumen
(arrow). It is separated from contrast material in the
duodenum by a radiolucent membrane.

5. • Fig GI 44-3 Caroli's disease.

6. • Fig GI 44-4 Congenital hepatic fibrosis.55

7. • Fig GI 44-5 Cholangitis. Communicating
hepatic abscess simulating localized cystic
dilatation of an intrahepatic bile duct.

8. • Fig GI 44-6 Cholangiohepatitis. A T-tube
cholangiogram demonstrates that the common
bile duct and intrahepatic duct (lower arrow) are
dilated. The upper arrow shows a moderately
dilated bile duct with short branches arising at
right angles to the duct.56
