ADPKD is one of the most common monogenic diseases characterized by the progressive development of renal and extrarenal cysts, with important variability in clinical expression ().It has worldwide prevalence and affects 0.2% of the general population, or every 400 to 1,000 births (), while isolated PLD is less prevalent than 0.01% (). Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. PKD cysts can slowly replace much of the kidneys, reducing kidney function and leading to kidney failure. Genetic factors, such as autosomal polycystic kidney disease and other congenital cystic diseases, may also be associated with the pathogenesis of peribiliary cysts [1, 2, 4, 5]. PKD cysts can reduce kidney function, leading to kidney failure. Liver cysts in ADPKD originate from biliary micro-hamartoma or focal proliferations of biliary ductules and from peribiliary glands. The autosomal dominant form of the disease is much more common than the autosomal recessive form. Polycystic kidney disease (also called PKD) causes numerous cysts to grow in the kidneys. Hereditary and relatively common, polycystic kidney disease (PKD) has long been thought to be progressive and irreversible, condemning its sufferers to a long, slow and often painful decline as fluid filled cysts develop in the kidneys, grow and eventually rob the organs of their function. Autosomal dominant polycystic kidney disease (ADPKD) affects up to 12 million patients worldwide and accounts for 10% of patients with end-stage renal disease (1,2).It is caused by mutations in the PKD1 and PKD2 genes and is characterized by abnormal proliferation of renal tubular epithelium, leading to massive kidney enlargement and progressive chronic kidney disease (1,2).
