title: Medullary renal dysplasia mimicking renal tumor in the Beckwith-Wiedemann syndrome.
abstract: The known association of Wilms' tumor with the Beckwith-Wiedemann syndrome has prompted a surveillance regimen for children with this problem. Herein we report a case of medullary renal dysplasia that was a new onset by documented ultrasound. The association of medullary renal dysplasia with Beckwith-Wiedemann syndrome is discussed as well as the management of this problem.
