Congenital adrenal hyperplasia

Congenital adrenal hyperplasia (CAH) is a form of adrenal hyperplasia related to a variety of autosomal recessive disorders in adrenal steroidogenesis. 

  • virilization of female fetuses 
  • electrolyte imbalance related to salt-losing crises 
  • dehydration
  • testicular masses

CAH is an autosomal recessive disorder of congenital cortisol synthesis enzyme deficiency:

  • 21 alpha-hydroxylase deficiency: ~ 90% of cases 5
  • 11 beta hydroxylase deficiency

Consider a normal neonatal adrenal: can be differentiated from CAH by the characteristic cerebriform appearance on sonography in CAH.
