Diffuse cystic echoes in the liver suggest the presence of hepatic cysts and are considered to be associated with congenital hepatic cysts, hepatic cysticercosis, and intrahepatic bile duct stones. Congenital hepatic cysts caused by embryonic abnormalities, liver cysts parasitized by hepatic cysticercosis, or cystic dilatation of the intrahepatic bile ducts caused by intrahepatic choledocholithiasis can be manifested as diffuse cystic echoes in the liver on imaging, which is suggestive of the presence of hepatic cysts. Congenital hepatic cysts without obvious symptoms usually do not need treatment, only dynamic observation; if liver cysts caused by liver cysts, intrahepatic choledocholithiasis should be treated with antiparasitic and surgical stone removal. In addition, if the diameter of liver cysts is large, combined with infection, compression of neighboring organs and tissues, etc., surgical treatment should be considered. Diffuse cystic echogenicity of the liver may also be related to other causes, it is recommended to consult a doctor in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
