Objective To analyze the CT features of rare rare bile duct cysts with cholangiocarcinoma in order to improve the understanding of this disease. Materials and Methods The clinical and CT data of 7 cases of bile duct cysts complicated with cholangiocarcinoma confirmed by pathology were analyzed retrospectively. Their clinical manifestations and imaging examinations were analyzed. Results Biliary cyst type I was found in 3 cases, type IV in 2 cases and type V in 2 cases. The type I was common in bile duct cysts, with 42.86% (3/7) of cholangiocarcinomas. In 7 cases, the main manifestation was mass in 3 cases, and the bile duct wall thickness was the main manifestation in 4 cases. There were 6 cases of delayed enhancement in CT dynamic scan, accounting for 85.71% (6/7). The accuracy of CT in diagnosing bile duct cyst with cholangiocarcinoma was 71.43% (5/7). Conclusion For the diagnosis of bile duct cysts with cholangiocarcinoma, CT is a valuable and non-invasive test method.
