Figure 3. Clinical course of the present case. Administration of oral and intravenous sodium chloride transiently increased the serum sodium concentration at first admission; however, fatigue and anorexia persisted. Hydrocortisone administration followed by levothyroxine replacement increased the sodium concentration up to 151 mmol/L. Desmopressin administration was required to attenuate the hypernatremia caused by the masked diabetes insipidus. Open circles with solid line represent serum sodium concentration, and closed circles with broken line represent urine specific gravity.
