title: Ultrasonic appearance of pyelogenic cysts.
abstract: Two cases, one in an adult and one in a child, of ultrasonically demonstrated cystic masses were shown to be pyelogenic cysts on contrast urography. Because of the similar appearance of pyelogenic and simple cysts of the kidney on sonography, contrast urography is important for the differential diagnosis.
