Survival and growth in a woman with untreated hypothalamic panhypopituitarism of 21 years' duration.
Show Full Abstract
A 29-year-old woman with evidence of a craniopharyngioma and documented panhypopituitarism is described. Clinical and laboratory evaluation revealed deficiencies of follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, growth hormone, prolactin, adrenocorticotropic hormone and antidiuretic hormone. Prompt release of several pituitary hormones was noticed after administration of the hypothalamic releasing hormones FSH/LH-RF and thyrotropin-releasing hormone, whereas insulin-induced hypoglycemia, levodopa, chlorpromazine and clomiphene citrate, all of which act at the level of the hypothalamus, did not alter basal pituitary secretion. The patient's height of 60 inches, despite panhypopituitarism, and the interpretation of the above data are discussed in the light of current concepts regarding the dynamics of the hypothalamic-hypophyseal system.
