Abstract:
A 66-year-old woman with rheumatoid arthritis experienced severe hyponatremia and hypoglycemia of repeated occurrence. Endocrinologic examinations revealed hypopituitarism and the metrizamide computerized tomographic scan showed a primary empty sella. No evidence of a pituitary or suprasellar tumor was obtained. During the 5-year follow-up, she remains well under replacement therapy and there are no signs of an intracranial tumor. The possibility of an autoimmune mechanism linked to the development of hypopituitarism is discussed.
