[Craniopharyngioma. A relatively uncommon etiology for an amenorrhea at the age of 45. Apropos of a case]. / Le craniopharyngiome. Etiologie peu commune d'une aménorrhée à l'âge de 45 ans. A propos d'un cas.

In reference to a case of secondary, pseudomenopausal amenorrhea, due to a craniopharyngioma discovered late, the need for a complete hypothalamo-hypophyseal exploration of every secondary, non-uterine, normogonadotrophic amenorrhea is reminded. The semiological value of the titration of serum prolactin and hypophyseal tests in lesions which are not only hypophyseal but also hypothalamic, is emphasized. In conclusion, the determining diagnostic contribution of tomodensitometry in tumors of this region is presented.
