Bilateral symmetrically enlarged hyperechogenic kidneys without cortico-medullary differentiation. Mild bilateral pelvicalyceal dilatation.

Case Discussion

Genitourinary anomalies are the most common reported abnormalities on antenatal ultrasound. Bilateral symmetrical echogenic kidneys with loss of cortico-medullary differentiation, mottled with hypoechoic foci and mild bilateral pelvicalyceal dilatation are suggestive of autosomal recessive polycystic kidney disease. It is a common cause of enlarged echogenic fetal kidneys. Most cases are associated with oligohydramnios. It is associated with perinatal morbidity and mortality due to renal insufficiency and associated other anomalies. No history of consanguinity between parents. Unfortunately, no postnatal data is available.
