Olfactory schwannoma is extremely rare. Schwannomas originate from Schwann cells and thus can grow anywhere in the nervous system that contain Schwan cells. Olfactory and optic nerves lack a Schwann cell layer, making it impossible for schwannomas to develop here [2–3]. The most common tumor developed within the anterior cranial fossa is a meningioma, with olfactory schwannoma and olfactory ensheathing cell tumor (OECT) being the rarest. Olfactory schwannoma is similar to OECT with respect to clinical and radiological characteristics, and the only way to distinguish between them is immunohistochemical staining [4].
