  • Title: Familial congenital Cushing's syndrome due to bilateral nodular adrenal hyperplasia.
    Author: Donaldson MD, Grant DB, O'Hare MJ, Shackleton CH.
    Journal: Clin Endocrinol (Oxf); 1981 May; 14(5):519-26. PubMed ID: 7307279.
    Abstract:
    Two siblings with congenital Cushing's syndrome due to bilateral nodular adrenal hyperplasia are described. The older, a boy, presented with severe hypertension and died soon after subtotal adrenalectomy. His sister, who had clitoral enlargement and showed persistent hyponatraemia, had a two-stage total adrenalectomy and is still alive. Investigations in the second case showed grossly elevated urinary cortisol metabolites, 17-oxosteroids and 3 beta-hydroxy-5-ene-steroids. These were not suppressed by dexamethasone, and plasma ACTH was undetectable, indicating that the disorder was not due to excessive ACTH secretion. Cell culture studies on the resected adrenals failed to demonstrate an abnormal pattern of steroid synthesis in vitro, and normal trophic responses were obtained with 1-24 ACTH and monobutyryl cyclic AMP. No stimulation of steroid synthesis was obtained with a range of polypeptide hormones, and the cause of the adrenal hyperplasia remains unknown.
