Liver cysts do not usually get smaller on their own. Liver cysts are cystic structures and are usually congenital. Due to the abnormal development of the embryonic biliary system in congenital liver cysts, a localized cystic cavity is formed, and fluid secreted by the bile duct epithelium collects in the locally dilated cystic cavity, and more and more cystic fluid forms a cyst. Most of the liver cysts are asymptomatic, if the patient does not have any discomfort, there is no need for treatment, adhere to the follow-up can be. When the cyst exceeds 5cm and is accompanied by discomfort or distension in the liver area, laparoscopic hepatic cyst opening and drainage or partial hepatectomy can be considered as treatment. If malignant transformation is suspected, pathological examination is needed for further confirmation. Liver cysts generally do not become smaller by themselves, and patients are advised to follow up regularly and consult the doctor in time to avoid delaying their condition.
