[Pituitary and hypothalamic metastases : 5 cases (author's transl)].

Five cases of metastatic cancer in the pituitary gland are reported, four of which were revealed by chiasmatic syndrome and one by diabetes insipidus. Transphenoidal surgical treatment was possible in three cases. This site of metastasis is considered exceptional because of its customary inactivity. It is probable that the metastasis most often remain unrecognized and so, it requires careful study of the slightest sign because of treatment possibilities.
