Paresia del III par craneal como manifestación de un corticotropinoma silente / Third nerve palsy as an expression of a corticotroph adenoma

Silent corticotroph adenomas (SCA) are pituitary adenomas inmunoreactive to ACTH without hormonal overproduction and they form the 3 percent of the pituitary adenomas. Unlike the ademonas that cause the Cushing’s disease, frequently the SCA are aggressive macroademonas and their clinical expressions are the compromise of nearby structures with or without pituitary apoplexy. Frequently, the treatment chosen is a surgical procedure, albeit the total resection difficulties. The SCA are not diagnosed until an anatomopathological and immunohistochemical study is carried out. In this document, a case study of a woman diagnosed with a clinically silent macrocorticotroph adenomadiscovered by a third nerve palsy is explained.
