Abstract:

In recent years， with gradual development of imaging technology and widespread application of chest CT during pandemic and post-pandemic era， the diagnostic rate of hepatic cystic lesions has been gradually elevated. Hepatic cystic lesions can be divided into benign and malignant types. Benign hepatic cystic lesions mainly include simple hepatic cyst， polycystic liver disease， hepatic echinococcosis，Caroli disease， bile duct hamartoma and intrahepatic biliary cystadenoma， etc. Malignant hepatic cystic lesions comprise intrahepatic biliary cystadenocarcinoma. Hemorrhage and infection are common complications of hepatic cysts. Although benign hepatic cystic lesions are dominant， the occurrence of malignant hepatic cystic lesions should be monitored in clinical settings. It is necessary to comprehensively consider the number，location， size and nature of the cystic lesions and physical condition of the patients and choose different treatment methods in clinical practice. Surgery is the main treatment for patients with hepatic echinococcosis.When patients are clinically diagnosed with cystadenoma， surgical resection should be considered in a timely manner. Extensive attention should be diverted to follow-up and examination for patients with Caroli disease and bile duct hamartoma in case of the incidence of cholangiocarcinoma. In this article， the types， differential diagnosis and treatment options of hepatic cystic lesions were reviewed based on clinical experience.
