Pituitary adenomas that are not hormone-secreting are probably the most common pituitary tumors and may be present in as much as 10–25% of the population. Although the vast majority of such tumors are completely asymptomatic, some patients with large tumors present with visual-field disturbances, headaches, or hypopituitarism. The introduction of the newer radiographic techniques of tomography of the sella at 1 to 2-mm cuts using hypocycloidal movement has brought forth the information that we may now be able to diagnose nonfunctioning microadenomas in patients.
