Postadrenalectomy pituitary adenoma (Nelson's syndrome) in childhood: clinical and roentgenologic detection.
Following total adrenalectomy in Cushing's syndrome associated with adrenal hyperplasia, but not with adrenal adenoma or malignancy, elements of the pituitary may be stimulated to grow rapidly and even aggressively. There is strong evidence to support the idea that there is a pre-existing tumor in many, if not all, of these cases. In some, the tumor may be too small to deform the sella turcica. After adrenalectomy, these patients should be observed carefully and frequently for hyperpigmentation, visual field defects, and sella turcica enlargement.
