GH deficiency with previous questionable microadenoma. The majority of the pituitary stalk is thin and non-enhancing. There is no discernible pituitary lesion. The pituitary gland is not enlarged or atrophic. The posterior pituitary bright spot appears to be intact, although there is focal T1 hyperintensity along the upper tuber cinereum as well. The optic apparatus and cavernous sinuses are intact. The cerebellar tonsils are perhaps slightly low-lying.
Unchanged hypoplasia of the pituitary stalk without a discernible pituitary lesion. Pituitary hypoplasia can be associated with a mutation in the growth hormone–releasing hormone receptor gene.
