A schwannoma, also known as neurilemmoma is a tumor of the nerve sheath, occurring in myelinated nerve cells. They arise from the Schwann cells of the peripheral nervous system and are almost always benign. Schwannomas constitute 25-45% of tumors of the head and neck. About 4% of head and neck schwannomas present as a sinonasal schwannoma.[1] Schwannomas almost always occur as solitary lesions. [2] A case of schwannomas arising from the membranous part of the nasal septum presenting as a cystic swelling is reported
