title: [Nonfuntional pituitary adenomas: evaluation of 36 patients].
abstract: We present our experience with 36 cases of nonfunctional pituitary adenomas. These tumors were divided into non reactive and inactive in agreement with the immunohistochemical study. They present with visual symptoms, mainly bitemporal hemianopsia; they were macroadenomas, either invasive or non invasive, in both groups. The treatment is surgical using the transsphenoidal approach. Total resection was possible in about 40% of the cases. Visual improvement occurred in 90% of the patients.
