It's an easy one to fix and generally resolution is good.

This depends on whether the tumor is a primary anterior pituitary
adenoma or a craniopharyngioma.  Both are benign.  Both may affect
vision via compression of the optic nerve, and both may affect the
body's hormonal system.  Malignant tumors arising in the pituitary or
next to the pituitary are very rare.

I believe that craniopharyngiomas have a higher recurrence rate.  I
have seen very few patients with pituitary tumors.  I diagnosed one
based upon the results of visual fields and a careful history.
