When large portions of a cat's renal parenchyma -- the functional tissue of the animal's kidneys which are normally differentiated -- are displaced by multiple cysts, the medical condition is referred to as polycystic kidney disease. They occur as simple fluid-filled structures, with a diameter of < 1 cm up to 30 cm and scattered on both sides of the liver. Apart from liver cysts, it exhibits few extrahepatic manifestations, and the majority of patients with this condition are asymptomatic or subclinical.

GEThere are two forms of polycystic liver disease: polycystic liver disease in isolation, in which patients have cysts only in the liver, and autosomal dominant polycystic kidney disease, in which patients have cysts in both the liver and the kidney. Autosomal dominant polycystic kidney disease is one of the most common serious hereditary diseases, found in 1:400 to 1:1000 individuals, and by far the most common hereditary cause of end stage renal failure (ESRF) 6.
