RESUMO
RATIONALE: Some diseases contribute to hypopituitarism without clinical manifestations and the glucocorticoid therapy may unveil central diabetes insipidus. The condition is rare and usually causes problems for clinical physicians. PATIENT CONCERNS: A 59-year-old woman presented to our hospital due to facial numbness and persistent eyelid heaviness. DIAGNOSIS: Physical examination and cerebrospinal fluid examination supported a diagnosis of Guillain-Barre[Combining Acute Accent] syndrome. Magnetic resonance imaging showed an empty sella. Hormone test indicated hypopituitarism. INTERVENTIONS: The patient received intravenous immunoglobulin and glucocorticoid. Central diabetes insipidus appeared after 20 days. Subsequently, the patient was prescribed 1-desamino-8-D-arginine vasopressin and prednisone. OUTCOMES: During 6 months' follow-up, the patient's urine output was gradually reduced to normal level. LESSONS: This case indicated that hypopituitarism may be caused by an empty sella and be masked by adrenal insufficiency. Central diabetes insipidus may present after glucocorticoid therapy.
