Polycystic kidney disease, autosomal dominant: The most common form of polycystic kidney disease characterized by the progressive development of innumerable cysts in the kidneys, causing hypertension, renal pain, and renal insufficiency (kidney failure). Other features of the disease can be cysts in other organs, such as the liver and 'pancreas, intracranial aneurysms, dilatation (widening) and dissection of the aorta, and abnormalities in the heart valves.
