[Diabetes insipidus in sarcoidosis].

Sarcoidosis is a generalized disorder which involves the central nervous system in 5 per cent of patients presenting with the disease. We describe the case of a 22-year-old man who developed central diabetes insipidus with a daily urine production of 14,81 seven weeks after diagnosis of pulmonary sarcoidosis and parotid gland enlargement. Computed tomography showed a contrast enhancement of pituitary gland and stalk, no other intracranial manifestations were demonstrated. Intranasal administration of synthetic antidiuretic hormone (ADH) reduced urine volume to normal levels immediately. After discontinuation of 15 months therapy with corticosteroids and administration of ADH for 29 months spontaneous urine volume didn't exceed 31. The patient has been free of symptoms since discontinuation of therapy.
