Growth in Cushing syndrome.

Pre- and post-operative growth was analysed in eight children with Cushing syndrome. Six children had Cushing's disease; three of them were treated by bilateral adrenalectomy and three by transphenoidal pituitary adenectomy. One child had an adrenocortical adenoma and another primary adrenocortical nodular dysplasia. The typical cushingoid habitus was not always present during hypercortisolism. In contrast, abnormal deceleration of longitudinal growth and increase in relative weight were constant. The slowing of growth started 0.2-5.1 years before diagnosis. In four children these changes concurred. In three others the excessive weight gain preceded the slowing of growth, by 2.5-7.0 years. In one patient the deceleration appeared first; this was a girl with concomitant coeliac disease. This pattern of growth change occurring before (normal slowing of growth in) late puberty should raise the possibility of hypercortisolism. There was a suggestion of a better growth recovery in Cushing disease after pituitary adenectomy than after bilateral adrenalectomy.
