Varying Appearances of Cholangiocarcinoma: Radiologic-Pathologic Correlation

Thought this might be of interest. The link below has some interesting information on CT imaging and other things I didn’t know about CC

Morphologic Classification: Radiologic-Pathologic Correlation
According to the morphologic classification system proposed by the Liver Cancer Study Group of Japan (,5), cholangiocarcinoma is classified into mass-forming, periductal infiltrating, and intraductal growth types (,Fig 5). Traditionally, extrahepatic bile duct cancer has been classified as nodular, sclerosing, or papillary (,3), corresponding to the mass-forming, periductal infiltrating, and intraductal growth types of intrahepatic cholangiocarcinoma, respectively. Classification based on gross morphologic characteristics is valuable for the interpretation of imaging features and the development of a differential diagnosis. It is also useful for predicting tumor dissemination and prognosis and for planning the surgical approach (,35–,37).
