ABSTRACT
Clinical findings diagnosis Pituitary adenomas cause their symptoms by abnormal hormone secretion (found in about 70% of pituitary adenomas) or by compression of normal glandular and neural structures.11,12 As macroadenomas outgrow the sella turcica, they compress neural structures including ocular motor nerves laterally and the optic chiasm and hypothalamus superiorly. An occasional pituitary adenoma erodes the floor of the sella turcica and presents as a mass in the sphenoid sinus or nasopharynx.
