Abstract: | Autosomal dominant (adult type) and autosomal recessive (infantile type) polycystic kidney disease are 2 distinct forms of
hereditary cystic renal disease with differing pathologic and clinical features. Glomerulocystic kidney disease is probably
a separate entity, whose pathologic features may closely resemble those of autosomal dominant polycystic kidney disease, especially
in small infants. An example of each of these conditions in a small infant is presented, all of which had sonographically
detectable cysts. Pathologic correlation was available in each case. While there are typical sonographic features of autosomal
dominant and autosomal recessive polycystic kidney disease in newborn and young infants, there is no specific appearance of
either condition, and glomerulocystic kidney disease can apparently resemble either one. Other investigations, particularly
family studies and pathologic verification, are important in order to establish the correct diagnosis. |
