Comments upon the classification of infantile polycystic diseases of the liver and kidney, based upon three-dimensional reconstruction of the liver

Three-dimensional reconstructions of portal tracts of two babies with different forms of infantile polycystic disease of the kidney and liver, and of a child with congenital hepatic fibrosis, have shown important differences between these three conditions. A strong plea is made for the application of this technique, and of microdissection of kidneys, to a large series of cases in order to develop a valid classification of these conditions.
