Liver cysts are usually benign lesions with internal fluid. On MRI findings, the T2 item may show a particularly bright round or round-like lesion, and most can be definitively diagnosed. For some solid or unknown lesions, the nature of the lesion can be further confirmed on MRI using contrast and enhancement. For hepatic cysts, MRI can be used to establish the diagnosis, but care should be taken to differentiate hepatic cystadenoma, choledochal cysts, and hepatic cysticercosis. MRI plain plus enhancement plus MRCP is recommended to identify the appropriate disease more effectively. Magnetic resonance MRCP of hepatic cysts can effectively determine whether the cysts are connected with the bile ducts, and magnetic resonance scanning and enhancement can further identify whether there are relevant prominent lesions in the patient’s cysts, so as to differentiate them from hepatic cystic adenoma and cystic adenocarcinoma. Ordinary liver cysts with no symptoms do not need treatment and should be followed up with regular checkups. However, if the cysts increase in size and cause corresponding pressure symptoms, abdominal mass, infection, biliary fistula, etc., then further treatment is required under the guidance of the doctor in a timely manner.
