Autosomal dominant polycystic kidney disease (ADPKD)
This section is from the same neonatal kidney illustrated grossly in the previous slide. This entity is usually
easily differentiated grossly and histologically from the kidney of ARPKD because of its more obvious
cysts. The kidney in Meckel-Gruber syndrome can have a very similar appearance but that syndrome
can usually be recognized by its extrarenal features such as polydactyly and posterior encephalocele.
