Liver cysts are associated with trauma, tumors, inflammation, and other factors. Kidney cysts are related to infection, stones, gene mutation and other factors. 1. Liver cysts: congenital liver cysts, caused by embryonic developmental disorders; traumatic liver cysts can be caused after liver trauma; inflammation of gallbladder or stone obstruction causes cystic dilatation of bile ducts, which can cause inflammatory liver cysts; teratomas and cystic adenomas of the liver can cause tumor liver cysts. 2. Kidney cysts: Infection or stones can cause destruction of the surface structure of the kidney, resulting in the formation of closed round cavities and eventually forming kidney cysts; hereditary kidney cysts are related to gene mutation; improper diet, overwork and other factors may stimulate the kidneys and induce kidney cysts. To confirm the diagnosis of liver cysts or renal cysts, it is recommended to go to the hospital.
