Pituitary function and structure were assessed in 69 endemic cretins from western China. In hypothyroid cretins (TSH greater than 10 mIU/l), CT imaging of the pituitary revealed adenoma in five of 20 (25%) and partially empty sella (PES) in a further eight of 20 (40%). The majority of tumours were microadenomas and showed a relation with higher levels of serum TSH but not with duration of hypothyroidism. Dynamic pituitary testing with TRH and GnRH in four patients with adenoma on CT gave a flat TSH response but significant rises in serum PRL, GH, LH and FSH concentrations. Hyperprolactinaemia (greater than 350 mIU/l) was present in hypothyroid cretins only (13 of 26; 50%) and serum PRL showed a curvilinear relation with serum TSH levels (r = 0.7, P less than 0.0001). Hypogonadism was seen in approximately half the cretins with high PRL levels. Our data suggest that severe protracted thyroid hormone deficiency may result in thyrotrophin adenomas of the pituitary gland. Disturbances of growth, puberty, and sexual function in endemic cretins are explained by the secondary effects of thyroid hormone deficiency on pituitary function.
