Right lobe cystic lesion of the liver with calcified cystadenoma is not life threatening, it is a benign tumor and can be treated minimally invasively if necessary. Cystic lesion of the right lobe of the liver is clinically suggestive of the presence of liver cysts, clinically simple liver cysts are not very harmful, it is recommended to carry out liver ultrasound or hepatobiliary CT examination every 6 months to a year; when the diameter of liver cysts is larger than 5 centimeters and the presence of abdominal distension and other symptoms, minimally invasive treatment can be considered, such as laparoscopic cysts opening and drainage, partial hepatectomy. Cystadenoma of the liver is also a benign lesion. When liver ultrasound is performed and cystadenoma of the liver is found to grow faster, it needs to be resected for pathological examination to determine whether there is a malignant problem. Clinical findings of cystic lesions in the right lobe of the liver associated with hepatic cystadenomas are seen in the hepatobiliary surgery department of a regular hospital.
