Abstract:Intrahepatic biliary cystadenoma (IBC) is a benign tumor with low incidence, unknown etiology and lack of specificity in clinical symptoms.It is easy to be confused with liver diseases such as liver cyst, liver abscess and liver echinococcosis.IBC progresses slowly, but is at risk of malignant transformation.The principle of treatment is early surgical removal of the tumor completely.A case of IBC was reported retrospectively.Ultrasound examination of the abdomen in this case revealed cystic tumor, anechoic areas in the liver, contains multiple separate liquid dark areas and light bands floating.Pathological examination revealed that the cyst wall was composed of fibrotic tissue, with local ovarioid stroma and a single layer of cubic/columnar epithelium.It was consistent with a mucinous cystadenoma of the bile duct.To report the image and diagnosis and treatment analysis of this case, aim to improve the understanding of IBC and reduce the incidence of misdiagnosis.
