Grade III adenomas are small or large locally invasive tumors that cause bony erosion of the sella turcica
The sella turcica is often enlarged, and there may occasionally be intrasellar herniation of the anteroinferior portion of the third ventricle or optic nerves/chiasm.
MRIs also show whether the lesion has invaded the sella turcica, whether the lesion displaces the chiasm, and whether it invades the hypothalamus, as well as the location of adjacent major blood vessels.
A transcranial approach or a craniotomy is indicated when the tumor extends beyond the boundaries of the sella turcica, when an unrelated pathology such as a parasellar aneurysm is suspected, or when the neurosurgeon suspects a fibrous tumor that cannot be completely removed by the transsphenoidal approach.
