title: [Late onset hypopituitarism due to hypoplasia of the adenohypophysis with invisible stalk and ectopic neurohypophysis in a 67-year-old patient].
abstract: Congenital hypopituitarism due to pituitary stalk and anterior pituitary hypoplasia accompanied by an ectopic posterior pituitary lobe is a rare disorder causing multiple hormone deficiencies. Clinical signs can be present at birth (hypoglycemia, prolonged jaundice and micropenis) and there can be severe growth restriction. Therefore, diagnosis is usually performed in childhood. We present the uncommon case of a 67-year-old man with hypopituitarism due to hypoplasia of the anterior pituitary and pituitary stalk together with an ectopic posterior pituitary who presented symptoms of hyponatremia due to adrenocorticotropic hormone deficiency.
