Liver cysts are categorized into parasitic and non-parasitic liver cysts. Parasitic liver cysts contain mostly parasitic worms and non-parasitic liver cysts contain cystic fluid.
1. Parasitic liver cysts: most popular in developed areas of the world animal husbandry. Mostly seen in fine-grained echinococcus tapeworm or multi-housed echinococcus tapeworm infection. Humans accidentally eat the eggs in the duodenum hatch, through the intestinal mucosa of the small veins into the portal vein, parasitized in the liver or lungs, and then spread throughout the body by the pulmonary circulation.
2. Non-parasitic liver cysts: the etiology is unknown. It is generally believed to be caused by abnormal development of intrahepatic vagal bile ducts, intrahepatic bile ducts, and lymphatic ducts during the embryonic period.
In early embryonic development, the hepatic ducts grow too much, and some of them are left behind to form cysts due to secretion aggregation; in mid-embryonic development, the small intrahepatic bile ducts produce too much, and some of them are not connected with the bile ducts and form cysts with fluid retention; in embryonic development, the abnormalities of the development of the liver, the cysts are formed with secondary inflammation and fluid retention in the hepatic ducts.
When liver cysts occur, it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor to avoid delaying the condition.
