Liver cysts are detected by physical examination, and after the diagnosis is clear, patients can be reviewed regularly. If the maximum diameter of the cyst is less than 5cm, it can be considered to continue to be observed; if the maximum diameter of the liver cyst is more than 5cm, it is necessary to carry out ultrasound-guided perforation and drainage according to the location of the cyst or laparoscopic decapitation and drainage of the cyst. After the surgical treatment, the blood routine and liver function should be checked in time. For patients with liver cysts found during physical examination, the nature of the cysts should be further clarified, whether they are simple cysts or parasitic diseases of the liver, such as hepatic cysticercosis. In addition, for some elderly patients, it is also necessary to further exclude whether there is a metastatic tumor in the liver, and if necessary, need to carry out an MRI of the upper abdomen.
