Cushing's Syndrome Presenting with Hyponatremia.

We present a case of Cushing's syndrome that presented with hyponatremia. A 64-year-old obese woman presented to the hospital emergency service complaining of a high fever, hypertension, and generalized oedema. During the examination, the patient suddenly became confused and lost consciousness. She was admitted to the intensive care unit. In addition, blood was drawn to measure the cortisol and ACTH levels, and urine samples were sent for analysis. Adenoctomy was performed through unilateral surgical treatment. Postoperatively, many of the complications arising from Cushing's syndrome disappeared. She healed quickly, and her complaints over the last 10 years disappeared completely within a few months.
