The primary empty sella an endocrine study on 12 cases.
Twelve patients (10 women and 2 men) with a primary empty sella turcica were studied. Endocrine function tests were performed as follows: growth hormone (GH) was measured after insulin-induced-hypoglycaemia, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) after LH-releasing hormone, thyrotrophin (TSH) and prolactin after thyrotrophin-releasing hormone; pituitary reserve of adrenocorticotrophin (ACTH) was determined by measurement of plasma cortisol after lysine-vasopressin and 11 deoxycortisol after metyrapone. Five of the patients (group A) had no endocrine disturbance. Seven patients (group B) had a hypothalamo-pituitary disorder. Two of them had panhypopituitarism which appeared in one case after meningoencephalitis and in the other after a severe cranial trauma. In two cases an amenorrhoea-galactorrhoea syndrome with increased prolactin level (68 and 230 ng/ml) led to a diagnosis of a prolactin producing adenoma, which was confirmed by surgery. Finally three cases of amenorrhoeagalactorrhoea, with normal prolactin level, and/or diabetes insipidus remained unexplained. However, no causal relationship could be demonstrated between the pituitary disturbance and the "empty sella". Primary empty sella turcica is therefore a neuroanatomical and neuroradiological entity with no endocrine implication. A pituitary disorder might suggest a microadenoma or an incidentally associated disease.
