Morphological optic nerve changes in a patient who has not undergone surgery for her giant pituitary adenoma: a case report

Abstract

We report a lethal case of a female patient who has not undergone surgery for her giant invasive infrasellar/endosellar/suprasellar/parasellar/retrosellar pituitary adenoma. The paper presents results of histological examination of optic nerves and considers the mechanisms of vision loss in prolonged chiasmal and optic nerve compression.
