Permanent Central Diabetes Insipidus with Complete Regression of Pituitary Stalk Enlargement After 4 Years of Follow−up

چکیده
A 14 year-old patient was admitted because of a history of polyuria and polydipsia. A diagnosis of central diabetes insipidus (CDI) accompanied by growth hormone (GH) and gonadotropin deficiency was made. Hypophyseal magnetic resonance imaging (MRI) of the patient demonstrated isolated pituitary stalk enlargement. Although GH deficiency and gonadotropin deficiency were transient, CDI was persistent despite the regression of the pituitary stalk enlargement over the 4 years of follow-up.

متن کاملLymphocytic hypophysitis with a long latent period from onset of central diabetes insipidus to development of pituitary enlargement.
A 61-year-old man presented with central lymphocytic hypophysitis. Initial pituitary MRI imaging was normal, except for loss of the "bright spot" of the posterior lobe. A diagnosis of idiopathic diabetes insipidus was made. Two years later, pituitary gland enlargement with panhypopituitarism was detected. Eight months after commencing a replacement dose of corticosteroid, the pituitary enlargem...

Four patients had an in...
