Multicystic dysplastic kidney with contralateral pelviureteric junction obstruction (pediatric)
Presentation
Abnormal kidneys on antenatal ultrasound.
Patient Data
The right kidney is enlarged with numerous non communicating cysts of various sizes (up to 24 mm), replacing the entire normal renal parenchyma with intercystic echogenic areas (fibrous parenchyma).
The left kidney is normal in size with moderate hydronephrosis, dilated renal pelvis and collapsed proximal ureter, suggestive of pelviureteric junction obstruction.
Case Discussion
Ultrasound features suggestive of a right multicystic dysplastic kidney (MCDK) with associated left pelviureteric junction obstruction. This association was already described in the literature.
