Onji M: Isolated ACTH deficiency with Graves’ disease: a case report

Abstract. A 60-year-old man was hospitalized with complaints of general malaise and weight loss. On admission, ACTH and cortisol levels were low, and thyroid function tests revealed hyperthyroidism. These findings and further examination led to a diagnosis of isolated ACTH deficiency (IAD) with Graves ’ disease. It is known that IAD is frequently associated with thyroid disease, but its association with Graves ’ disease is rare. The present case is worth noting, because some reports indicate that aggravation of associated Graves ’ disease may concomitantly aggravate adrenal insufficiency in patients with IAD. Key words: Isolated ACTH deficiency, Graves ’ diseas
