Management of non-functioning pituitary adenomas: surgery.

Pituitary 2018 Apr;21(2):145-153

Department of Neurological Surgery, Brigham and Women's Hospital, Harvard Medical School, 60 Fenwood Road, BTM, 4th Floor, Boston, MA, 02115, USA.

Non-functional pituitary adenomas (NFPAs) are benign tumors of the pituitary gland that do not over-secrete hormonal products, therefore, they are generally detected through symptoms of mass effect, including headache, vision loss, or hypopituitarism. There are multiple pathological subtypes of NFPAs, such as null cell adenomas, silent gonadotrophs, silent somatotrophs, silent corticotrophs, and silent subtype 3, all of which can be classified based on immunohistochemical studies and electron microscopy. Despite these numerous pathological subtypes, surgical resection remains the first-line treatment for NFPAs. Read More
