Cholangiolocellular carcinoma (CoCC) is a rare primary liver cancer that is difficult diagnose due to a lack of specific imaging findings. We herein report a case of CoCC accompanied by severe alcoholic cirrhosis. Dynamic computed tomography showed a low-density tumor with a faint surrounding enhancement. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging revealed iso-intensity in the hepatobiliary phase and a maximum tumor diameter of 53 mm. 18F-fluoro-2-deoxyglucose position-emission tomography was moderately positive (maximum standardized uptake value: 4.3). CoCC was diagnosed based on the pathological findings, including immunohistochemistry. We discuss the diagnostic imaging findings and review previous reports.
