Liver cysts are a relatively common benign disease of the liver and are classified as parasitic or nonparasitic liver cysts. Most of the clinical cases are congenital liver cysts, which are non-parasitic liver cysts. Congenital liver cysts grow slowly, and small cysts may be asymptomatic and only discovered incidentally during ultrasound or other abdominal procedures. When the cyst increases to a certain extent, it may compress the adjacent organs and cause symptoms such as postprandial fullness, nausea, vomiting, right upper abdominal discomfort and vague pain. Cyst rupture or intracapsular hemorrhage may manifest as acute abdominal pain, and sudden epigastric pain may occur in case of torsion of the cyst with a tip. In a few cases, the cyst may compress the bile ducts and cause obstructive jaundice. In case of intracapsular infection, the patient has chills, fever and leukocytosis. All of these symptoms can be cured after surgical removal or drainage of the cyst. A small percentage of liver cysts with congenital hepatic fibrosis, portal hypertension or progressive renal unit loss have a poor prognosis and eventually lead to death due to liver function, renal failure or corresponding complications. Moreover, in large cysts, a mass and hepatomegaly can be felt in the right upper abdomen, and the mass can move with breathing without significant pressure pain. Although liver cyst is a benign disease, but if the cyst is too large can also cause harm to the body, if the examination found this disease, should go to the regular hospital for further examination, whether the need for treatment according to medical advice.
