Types of Choledochal Cysts
- Type I: Fusiform cystic dilation of the extrahepatic duct and common bile duct; most prevalent type.
- Type II: A true diverticulum of the supraduodenal extrahepatic duct.
- Type III: Dilation is restricted to the intraduodenal bile duct, also known as choledochocele; located within the duodenal wall.
-
Type IV: Characterized by multiple biliary cysts with at least one affecting the extrahepatic bile duct.
- Subtype a: Involves intra and extrahepatic dilatation.
- Subtype b: Involves extrahepatic dilatation only.
- Type V: Intrahepatic biliary cysts only, which can be single or multiple; associated with Caroli disease when multiple intrahepatic cysts are present.
