Multicystic renal dysplasia

Abstract

Multicystic renal dysplasia, the most common form of cystic renal disease in the newborn period, is a clinically important consequence of abnormal nephrogenesis. It usually presents as an abdominal mass. The dysplasias are usually unilateral, but it can be bilateral, segmental or focal. The clinical presentation usually depends on the extent of the dysplastic involvement and the degree of the associated urinary obstruction. Here, we present a case of histologically multicystic renal dysplasia, which is ?bilateral. The left kidney showed typical radiological, gross and histopathological features of multicystic dysplasia, but the right kidney showed only radiological features of dysplastic cystic kidney.
