Ectopic Neurohypophysis: Report of Two Cases
Main Article Content
Abstract
ABSTRACT
A 24-year-old boy and a 19-year-old girl were referred to our clinic with idiopathic short stature and multiple pituitary hormone deficiencies. Case 1 presented with short stature, hypogonadism and hypocortisolism while the second case had hypothyroidism in addition to hypogonadism and hypocortisolism. Imaging studies with magnetic resonance (MRI) revealed transection of the pituitary stalk, a hypoplastic pituitary gland, and an ectopic neurohypophysis located at the proximal stump of the transected stalk in both cases. Evaluation of the morphology and the height of the pituitary gland by MRI of those cases with idiopathic growth hormone deficiency is an essential tool for the diagnosis of ectopic neurohypophysis.
