1) Prenatal ultrasound identified a cystic enlargement of the left kidney in the fetus.
2) After a preterm delivery, examination of the newborn found generalized edema, dysmorphic features, and a grossly edematous left MCDK.
3) Workup revealed renal failure. Imaging showed a small right kidney. The newborn was treated with peritoneal dialysis.
