title: Does pituitary stalk function improve with age?
abstract: Ectopic posterior pituitary hyperintensity on MRI is a common feature associated with growth hormone deficiency. The presence of at least some residual components of the pituitary stalk is necessary for adequate anterior pituitary function. Little is known about long-term change in pituitary function or MRI findings in patients with ectopic posterior pituitary and interrupted pituitary stalk. We describe a case of childhood growth hormone deficiency and hyperprolactinemia associated with absent pituitary stalk. As an adult, prolactin levels normalized and GH secretion improved associated with changes in MRI findings.
