title: [Segmental multicystic renal dysplasia: radiological findings and differential diagnosis].
abstract: Multicystic dysplasia of the kidney is the second most common cause of renal masses in newborns after hydronephrosis and the most frequent cause of cystic masses in childhood. We present the case of a cystic renal mass in an infant that was definitively diagnosed at histological examination to be segmental cystic dysplasia. Cystic renal dysplasia usually involves an entire kidney, and segmental multicystic renal dysplasia is rare. We review the etiology and pathogenesis of this entity, the radiological findings, and the main differential diagnoses with the aim of establishing the correct diagnosis and differentiating this entity from other focal cystic kidney lesions affecting children.
