Childhood Cushing disease: results of bilateral adrenalectomy

In view of the published reports of the successful correction of hypercortisolism in adult patients with Cushing disease by external pituitary irradiation and transsphenoidal pituitary microsurgery, leaving the patients with intact pituitary and adrenocortical function, we have reviewed the results of adrenalectomy in childhood Cushing disease seen at the Mayo Clinic. Twenty-seven patients were treated with total (16 patients) or subtotal (11 patients) bilateral adrenalectomy before the age of 20 years. Follow-up ranged from one to 27 years. Although hypercortisolism was corrected in all but one patient, 12 (45%) patients had roentgenographic evidence of a pituitary tumor and six (22%) of these required pituitary surgery. An additional six patients (22%) were pigmented, but had no abnormality on roentgenographic studies. The remaining nine patients (33%) were well, without evidence of pituitary tumor. We conclude that alternate forms of therapy should be considered for childhood Cushing disease.
