A short illustrated review of sellar region schwannomas.

INTRODUCTION: 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. LITERATURE REVIEW: We review the rare occurrence of sellar region schwannomas, their clinical presentation, operative management, outcomes, and the possible pathogenesis. ANALYSIS: 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.
