Liver cysts are a lesion of the liver and are a common clinical benign disease of the liver. Liver cysts are common benign diseases of the liver and are clinically categorized into parasitic and non-parasitic. The former is more common in liver cysts, and the latter can be divided into congenital, traumatic, inflammatory, and tumor cysts. Usually, liver cysts refer to congenital liver cysts, which can be further divided into solitary and multiple. Single hepatic cysts are rare, the cyst fluid is only a few milliliters in small cysts, and the cyst fluid can be more than 1,000 ml in large cysts. Multiple hepatic cysts mean that there are more than two cysts in the liver, and multiple hepatic cysts can be combined with bile duct stenosis, cholangitis, and hepatitis, which can cause liver function impairment in the late stage, and in very rare cases, may also cause cancerous transformation. Liver cysts usually have no obvious symptoms, but oversized cysts compressing the neighboring organs may cause corresponding clinical symptoms, such as stuffiness, distension and pain in the right quadrant of the ribs and epigastric region. Physical examination reveals limited elevation of the right upper abdomen with fluctuating sensation on touch. When there is bleeding in the cystic cavity, it can cause persistent dull pain; those with gastrointestinal compression have postprandial epigastric distension or nausea, vomiting; cysts compressing the biliary tract can appear jaundice. Therefore, patients with liver cysts must choose to consult a doctor in time and follow the doctor’s instructions for early standardized treatment to avoid aggravation of the condition.
