A short illustrated review of sellar region schwannomas.
BACKGROUND
In this short illustrated review, we present the case of a frontal lobe schwannoma without cranial nerve or sellar attachment and a sellar schwannoma which mimicked a pituitary adenoma.


METHODS
We review the rare occurrence of sellar region schwannomas, their clinical presentation, operative management, outcomes, and the possible pathogenesis.


METHODS
The absence of Schwann cells in the central nervous system and the absence of neighboring cranial nerves in these two cases raise issues of the pathogenesis of these rare but curious lesions.
