A dichotomous imaging classification for cholangiocarcinomas based on new histologic concepts

초록

We noted the limitations of applying conventional macroscopic patterns to classify the imaging features of cholangiocarcinoma (CCA). Therefore, we hereby propose a dichotomous imaging classification of "parenchymal" and "ductal" types, based on recent developments in the histopathologic concepts of CCA. This new imaging classification of CCA is simple and easy to apply, and can be useful to describe underlying carcinogenesis and correlate clinicopathologic characteristics with imaging patterns of CCA.
