MRI of ectopic posterior pituitary gland with dysgenesis of pituitary stalk in a patient with hypogonadotropic hypogonadism

Abstract

The ectopic posterior pituitary is a rare condition which is characterized by the ectopic location of posterior lobe of pituitary, pituitary stalk abnormalities, and associated clinical manifestations of anterior lobe related growth hormone dysfunction or less commonly multiple anterior pituitary dysfunctions. We present a rare case of posterior ectopic pituitary and pituitary stalk hypoplasia with isolated hypogonadotropic hypogonadism in a 36-year-old female patient.
