Cystic renal diseases: role of ultrasound. part II, genetic cystic renal diseases

Abstract

Kidney cysts are quite common in adults. Though small simple renal cysts in an adult over 30-40 years of age are not too unusual, however, if the same cysts are seen in a child, and especially if there are additional findings, then several diagnostic possibilities may come to mind. The role of ultrasound, together with the help of intravenous contrast agents and Doppler mode, are very critical in describing the morphologic features and follow-up of the complex or multiple and bilateral renal cysts. These sonographic signs are occasionally specific for diagnosis, but in many cases sonographic clues should be evaluated together with the other genetic and clinical data to reach diagnosis. The first part of this pictorial essay included the introduction into the subject and the classification of non-genetic cystic renal diseases. The key features for the non-genetic cystic renal diseases are illustrated. In the second part, eye-catching features of genetic cystic renal diseases are demonstrated. © 2022 Societatea Romana de Ultrasonografie in Medicina si Biologie. All rights reserved.
