This is the most frequent type (90-95% of the cases). Type IV is also a true choledichal cyst with dilatation of the entire extrahepatic duct with involvement of portions of the intrahepatic ducts. The intrahepatic ducts taper normally to the periphery, indicating that there is no obstruction. Type II and III are extremely rare and it is debatable whether or not these are true choledochal cysts. Type II is a diverticulum of the extrahepatic duct and many believe that this entity is not related to an anomalous pancreatico-biliary junction.
A number of pathologic conditions, however, resulting in either acute or chronic biliary tract epithelial injury may predispose to malignant change. Primary sclerosing cholangitis, an idiopathic inflammatory condition of the biliary tree, has been clearly associated with the development of cholangiocarcinoma in up to 40% of patients. Congenital biliary cystic disease, such as choledochal cysts or Caroli's disease, has also been associated with malignant transformation in up to 25% of cases. These conditions appear to be related to an anomalous pancreatico-biliary duct junction.
