MRI studies revealed a mass in the perisella region which extended into the
sella eroding the posterior sella floor. The mass extended from the superior
orbital fissue to the tentorial margin and involved the optic chiasm and
extended laterally to involve the right cavernous sinus, surrounding the right
internal carotid artery.
A transphenoidal approach was used to remove the tumor.
