Pictorial Essay


Pediatric renal cystic diseases include a variety of hereditary or non-hereditary conditions. Numerous classifications exist and new data are continuously published. Ultrasound is the primary technique for evaluating kidneys in children: conventional and high-resolution US allows a detailed visualization of renal parenchyma and of number, size and location of the cysts, hence representing the most important diagnostic imaging technique for the first diagnosis and follow-up of these young patients. The purpose of this pictorial essay is to review the spectrum of renal cystic lesions in children from simple, complex or malignant single cysts to the several poly/multicystic kidney diseases.


Cystic renal disease Kidney Neonatal Pediatric Ultrasound 


La patologia cistica renale in età pediatrica è costituita da svariate condizioni ereditarie e non. La letteratura propone diverse classificazioni, in continua evoluzione. L’ecografia rappresenta la prima metodica per la valutazione del rene nel neonato e nel bambino: l’esame con metodica tradizionale e con sonde ad alta risoluzione consente uno studio dettagliato del parenchima renale e delle cisti per numero, dimensioni e localizzazione. L’ecografia è pertanto il cardine nell’iter diagnostico e nel follow-up di questi piccoli pazienti. Obiettivo di questo lavoro è rivedere le peculiarità delle lesioni cistiche renali in età pediatrica: dalla cisti singola, semplice o complessa, allo spettro delle patologie multi/policistiche.
