Hepatic cystic solid occupations may suggest conditions such as hepatic cystadenoma or liquefaction necrosis of the original solid lesion. 1. hepatic cystadenoma. Hepatic cystic-solid space occupation refers to the presence of both cystic and partially solid components in liver lesions, which often suggests the occurrence of hepatic cystadenoma in clinical practice. 2. Liquefaction necrosis of solid lesions. In addition to cystadenoma, liquefaction and necrosis of the original solid foci of the liver, which makes the coexistence of cystic and solid components in the same foci, may also lead to cystic-solid hepatic space occupation on CT. If there is no obvious discomfort, small lesions can be left untreated after excluding the possibility of malignancy. Large lesions or lesions with accompanying symptoms or malignant potential should be actively treated with surgical resection. If there is cystic-solid liver occupation, it is recommended to consult a doctor for further examination to determine the nature of the cystic-solid liver occupation so as to decide the best treatment plan.
