Hepatorenal cysts are relatively common benign diseases, which can be classified as congenital, inflammatory, traumatic and tumorigenic. Clinically, congenital hepatorenal cysts are more common, and the specific etiology of the disease may be due to congenital causes, caused by developmental abnormalities during the embryonic period, and to a lesser extent, caused by trauma and inflammation. The diagnosis is usually clear based on clinical manifestations and ultrasonography and CT examination. At present, the treatment for liver and kidney cysts mainly has the following principles. Cysts that are relatively small and have no symptoms generally do not require special treatment and regular follow-up is recommended. If the cyst has larger symptoms and produces compression, cyst opening and drainage can be performed. If the cyst is infected and there is intracapsular bleeding, it is recommended that a window be placed to drain the cyst. In case of extensive polycystic liver or polycystic kidney, liver transplantation or kidney transplantation can be done if necessary.
