Recent Updates in the Imaging Diagnosis of Cholangiocarcinoma

ABSTRACT

Cholangiocarcinoma is a disease entity with a wide spectrum of imaging, histological, and clinical features as well as treatment options. At present, imaging studies are essential for the detection, characterization, staging, and resectability assessment of cholangiocarcinoma. This review article describes the imaging features of intrahepatic and perihilar cholangiocarcinoma and the considerations for interpretation of these features. In addition, we introduce the latest concepts regarding the classification system, carcinogenesis process, premalignant lesions, and treatment approaches for cholangiocarcinoma.
