Case report
Multicystic dysplastic kidney disease (MCDKD) is characterized by an architectural disorganization of the kidney and by varying degrees of histopathologic changes including presence of immature glomeruli, primitive tubules surrounded by fibromuscular collars, nests of metaplastic cartilage, tubular or glomerular origin of cysts, and atresia of the ipsilateral ureter. We describe a case of unilateral multicystic dysplastic kidney. An ultrasound investigation at 31st week of pregnancy revealed a hyperechoic, polycystic right kidney, without cortico-medullar differentiation (60 x 45 mm of diameter). The contralateral kidney and urinary bladder were normal. Postnatally the diagnosis was confirmed but the baby is doing well.
