The basic causes of hepatic cysts are simple hepatic cysts, polycystic liver disease, and hepatic cysticercosis. 1. Simple hepatic cysts: the etiology is unknown, but it is considered to be related to the developmental disorder of intrahepatic bile ducts and lymphatic vessels in embryonic period. Some patients with simple hepatic cysts can also be triggered by inflammation and infection, trauma, tumor and other factors. Most patients are asymptomatic, but the increasing size of cysts may cause symptoms such as postprandial fullness, nausea and vomiting, and vague pain in the right upper abdomen. 2. Polycystic liver disease: it belongs to autosomal dominant malformation lesions, which may be caused by the abnormal bile ducts being retained, shedding and expanding, and may also be caused by the biliary cilia defects prompting excessive proliferation of bile duct cells. Patients are prone to abdominal distension, ascites, jaundice and other uncomfortable symptoms. 3. Hepatic encystment: mainly due to infection with Echinococcus granulosus. The disease can develop through contact with parasite-infected animals, water and food contaminated with worm eggs. The disease will cause the patient often appear right upper abdominal pain, fever, nausea and vomiting, jaundice and other symptoms. For 60-year-old patients diagnosed with liver cysts, they should pay attention to adjusting their mindset and actively cooperate with doctors to take treatment measures in order to alleviate uncomfortable symptoms and improve the quality of life.
