Autosomal dominant polycystic kidney disease ADPKD , also sometimes more vaguely referred to as "adult polycystic kidney disease", is as the name would suggest, a hereditary form of adult cystic renal disease. The kidneys are normal at birth, and with time develop multiple cysts. That figure increases over time, such that essentially all patients eventually demonstrate cystic change. The risk of renal cancer is not increased. Macroscopically the kidney demonstrates a large number of cysts of variable size from a few mm to many cms , in both the cortex and medulla. They are filled with fluid of variable color from clear or straw colored to altered blood or chocolate colored to purulent when infected.

On imaging, it usually presents on ultrasound with enlarged echogenic kidneys with multiple small cysts. Liver involvement with coarse echotexture, biliary tract cystic changes, and portal hypertension may be evident, depending on the age and stage of hepatic fibrosis. ARPKD is one of the commonest inheritable infantile cystic renal diseases but is far less common than the autosomal dominant polycystic disease ADPKD , which affects adults.
There is no perceived gender or racial predilection. The age of presentation is variable and is divided into perinatal, neonatal, infantile and juvenile forms for the sake of simplicity one can think of only two groups: those that present around birth, and those that present later in childhood. There is an inverse relationship with severity of associated congenital hepatic fibrosis. Results from a mutation in the PKHD1 polycystic kidney and hepatic disease gene location on chromosome 6p.
This results in bilateral symmetric microcystic disease occurring in the distal convoluted tubules and collecting ducts. The number of ducts involved determines the age of presentation. If performed, a streaky appearance may be demonstrated, representing the ectatic collecting ducts.
The prognosis is poor in general but also significantly depends on the type. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Updating… Please wait. Unable to process the form. Check for errors and try again. Thank you for updating your details.

El carcinoma de la celula renal es encontrado en muy poca probabilidad en la enfermedad renal poliquistica autosomica dominante. El objetivo de este trabajo es presentar un caso tratado por insuficiencia renal cronica progresiva en el curso de una enfermedad renal poliquistica autosomica dominante, el cual sufre graves complicaciones y es intervenido quirurgicamente, encontrandose en el acto quirurgico la asociacion de un tumor con una enfermedad renal poliquistica autosomica dominante.
