[Prolactin-secreting pituitary gland adenoma. Present-day possibilities of diagnosis and treatment].

Among the 230 pituitary adenomas that we treated, 23 patients aging from 20 to 39 had a prolactin-secretary pituitary adenoma and were all demonstrating an amenorrhea-galactorrhea syndrom. It is not always very fast to establish the more and more frequently observed etiology of this clinical state, especially when the existence, or not, of a pituitary adenoma is concerned. A total endocrinological study (determination of serum prolactin and inhibition and stimulation tests) of all hypothalamic-hypophyseal-peripheric axis must be done, as well as precise radiological studies, able of showing small distortions of the sella turcica. On our patients, the diagnosis of a pituitary tumor and the surgical intervention have never been decided on the base of only one element of the diagnosis. We now think that only the presence, at the same time, of clinical, radiological and biological signs, however small they are, allows the decision for a surgical intervention when prolactin-secreting pituitary adenoma is suspected.
