WK 4 BILIARY TREE PATHOLOGY Diagnosis: Caroli disease

Biliary System - Caroli Disease - Segmental dilatation of intrahepatic bile ducts. Some stones with posterior shadowing may be see.

Caroli disease with a localized area with nonobstructive dilatation of the intrahepatic bile ducts (there are also fatty liver changes)

Todani classification of bile duct cysts - Type I: dilation of the extrahepatic bile duct. Type II: a bile duct diverticulum. Type III: a choledochocele: focally dilated, intramural segment of the distal common bile duct into the duodenum. Type IVa: dilation of the entire EHBD duct with extension to IHBD bile ducts. type 4b: multiple cystic dilations involving only the EHBD. Type V: Also known as Caroli disease which is cystic dilations of IHBD.
