Hepatic cysts are what are commonly known as “liver blisters”, which are structurally vacuoles in the liver that do not contain solid tissue. Using the analogy of the vacuole in a cheesecake, it may be easier to understand what a liver cyst looks like in the liver. Generally speaking, liver cysts are different from the tumors we often hear about. The cause of its formation, in most cases, is unknown to us and is probably congenital. However, there is a clinical phenomenon in which there is a higher chance of developing liver cysts with age. The following are the specific clinical manifestations. 1.Gastrointestinal symptoms When the cyst enlarges and compresses the stomach, duodenum and colon, it can cause symptoms such as postprandial fullness, loss of appetite, nausea and vomiting. 2, abdominal pain Large and heavy cysts can cause epigastric swelling discomfort, vague pain or mild dull pain. Sudden onset of severe pain or signs and symptoms of peritonitis suggest the occurrence of complications such as cyst bleeding or rupture, and chills and fever may appear. 3, abdominal masses The discovery of abdominal masses is the main initial manifestation in many patients. 4.Jaundice The cyst adjacent to the hilar can cause mild jaundice by compressing the hepatic duct or common bile duct, the incidence of which is low, occurring in only about 5% of cases. 5. Physical examination The main sign is a mass that moves with breathing when palpated in the abdomen. The surface of the mass is smooth, usually hard, and only part of it is cystic with fluctuating sensation. The location of the mass depends on the location of the cyst, but most of them are located in the right upper abdomen.
