Non-parasitic liver cysts are benign congenital disorders and are divided into isolated (solitary) and multiple cysts and polycystic livers, the latter mostly combined with polycystic kidneys. Hepatic cysts are mostly found in women and can be as small as a few milliliters or as large as several liters. The diagnosis of hepatic cysts is easily determined by B-mode ultrasound, which shows a well-defined liquid dark area. Care should be taken to distinguish them from liver cysts. Cystic lesions of other organs should be noted in multiple cysts. Most small cysts do not cause clinical symptoms and do not require treatment. Those with symptoms of compression should be treated. Cyst puncture and aspiration is feasible for those with huge cysts that are not suitable for surgery to obtain temporary relief of symptoms. Isolated large cysts can be surgically opened and part of the cyst wall removed. If the cyst is confined to one lobe of the liver, the lobe can also be removed. Cysts complicated by infection or connected to the biliary tract should be treated by resection for better results.
