Hepatic cystadenoma, also known as intrahepatic cholangiocarpal cystadenoma, is a rare benign tumor of the liver, and although the disease is most common in women, it can still occur in men. The occurrence of hepatic cystadenoma is mainly related to abnormal embryonic development leading to vagal bile ducts in the liver, residual preimplantation intestinal or ectopic ovarian tissue, and endocrine disorders leading to an abnormal proliferation of glands around the bile ducts. Approximately 85% of hepatic cystadenomas occur in the intrahepatic bile ducts, with a small percentage occurring in the extrahepatic bile ducts or gallbladder. About 85% to 90% of the patients are middle-aged or elderly women, so women over 40 years of age and those who have a history of taking birth control pills are more likely to develop the disease, but women are not the only ones who may suffer from this disease, and men have a certain degree of probability of developing the disease as well. The clinical manifestations of the disease vary greatly, and may include abdominal distension, abdominal pain, jaundice, nausea and vomiting. Therefore, both men and women need to consult a doctor for a clear diagnosis and active treatment if symptoms occur.
