A very small number of patients with polycystic liver do not develop the disease in their lifetime, and are only found to have polycystic liver by chance during physical examination. Polycystic liver is an autosomal dominant disease with hereditary and family history, and is often complicated with polycystic kidney. The size of polycystic liver varies, the small one is only visible by microscope, the growth is slow, there are no obvious clinical symptoms, and generally it does not affect the liver function, so there are very few patients with polycystic liver who do not have any disease in their whole life, and they are only found to have polycystic liver in medical checkups. However, in most patients with polycystic liver, the cysts will gradually increase in size with the passage of time, resulting in compression symptoms, and in some cases, bleeding and infection, and even leading to serious liver dysfunction. If the condition of polycystic liver is found, no matter the size of the cysts, it should not be taken lightly, and it is recommended to follow up regularly or standardize the treatment under the guidance of the doctor.
