[A case of pituitary stalk tumor diagnosed with magnetic resonance (MRI)].
Authors present a case of 28-year old female with anterior hypopituitarism and diabetes insipidus, with properly functioning anterior pituitary cells as showed by means of measuring pituitary hormones in response to neurohormones i.v. injections. Magnetic resonance imaging revealed neoplastic tissue in the pituitary stalk destroying supraopticohypophysial and paraventriculohypophysial tracts, as well as portal blood system, thus preventing release of vasopressin and these hypothalamic neurohormones from accessing anterior pituitary.
