Diffuse hyperplasia. CT shows bilaterally enlarged adrenal glands in a patient with Cushing's disease (A). The adrenal gland is also diffusely enlarged and displays a normal zonation. In contrast to ectopic ACTH-related diffuse hyperplasia, the zonation of the cortex is often conserved in pituitary ACTH-dependent hyperplasia (B).
