Cholangiocarcinoma is a challenging disease in terms of diagnosis and treatment. The worldwide incidence of this uncommon disease is on the rise and it remains the second most common primary hepatobiliary malignancy. The radiologic presentations of cholangiocarcinoma are extremely diverse because these tumors vary considerably in terms of location, histologic subtype and growth pattern. Magnetic
cholangiopancreatography (MRCP) is the radiologic modality of choice as the mainstay of diagnosis in cholangiocarcinoma. It provides visualization of the tumor location and displays the longitudinal extent along the biliary tree as well as vertical spread into the adjacent hepatic parenchyma and vessels. Surgery is the main curative option for the patient, so resectability of the tumor should be precisely assessed. The knowledge of radiologist about imaging manifestations and preoperative staging of cholangiocarcinoma play a major role in management of this devastating malignancy. In this presentation, imaging findings in different types of cholangiocarcinoma will be reviewed and hot topics in tumor resectability and resection will be discussed
