Description
		
This specimen represents one-half of a kidney grossly enlarged by multiple cysts up to 3 cm. in 
diameter. The general form of the kidney is retained, while the external surface is distorted by a 
multitude of thin-walled cysts. The majority of the cysts contain clear fluid, although some contain 
blood. Approximately 1/3 of patients with this condition have cysts in the 
liver and there is also a clinically significant association with aneurysm of the cerebral arteries.
