title: Spontaneous intermittent MRI changes of a pituitary stalk lesion causing diabetes insipidus and amenorrhea.
abstract: Lymphocytic infundibulo-neurohypophysitis is a rare disorder. We report the case of a 29 year-old woman with diabetes insipidus and amenorrhea, in whom the magnetic resonance imaging demonstration of a pituitary stalk lesion was intermittent. We suggest that, in patients with endocrine dysfunction and positivity of circulating antipituitary antibodies at high title, magnetic resonance imaging should be repeated after few months, if negative.
