Unilateral polycystic kidney disease

Although involvement of the kidneys by the adult form of polycystic kidney disease may be asynchronous or asymmetric, the disorder is thought of as invariably bilateral according to some pathologists [1]. Scattered cases of unilateral polycystic kidney disease have been reported in the urobogic but not the radiobogic literature. These are either ignored, interpreted as misdiagnosis, or frankly accepted as inexplicable by most authors [i]. We report a very unusual case recently seen in our hospital.
