title: Prenatal diagnosis of autosomal recessive polycystic kidney disease by ultrasonography and magnetic resonance imaging.
abstract: Autosomal recessive polycystic kidney disease is a relatively rare congenital disease affecting the kidneys and liver. We noticed the kidney abnormality at 22 weeks gestation and observed the patient till the delivery at 36 weeks of gestation. The ultrasonographic features consisted of bilaterally enlarged hyperechogenic kidneys, oligohydramnios, lack of distention and difficulty in identifying the fetal urinary bladder. The serial sonographic features of the kidneys changed as pregnancy progressed. The kidney cysts gradually changed in size, shape and renal texture, but the umbilical velocimetry and the kidney circumference/abdominal circumference ratio did not change. Magnetic resonance imaging also showed similar characteristic features as observed by ultrasonography.
