Polycystic disease of the kidney and liver in an adult Persian cat.

Polycystic disease of the kidney and liver was diagnosed in a 10-year-old spayed female Persian cat. Previous reports of renal and hepatic polycystic disease in dogs and cats have described only juvenile forms, with death at an early age. The cat of this report had large, fluid-filled kidney and liver cysts, compared with the relatively small, spongiform cysts of puppies and kittens. The clinicopathological findings in this adult Persian cat are comparable to the adult form of renal and hepatic polycystic disease of man.
