Neurilemmoma (schwannoma) is a benign peripheral nerve sheath tumour that rarely occurs in the nasal cavity. Lesions that present in the paranasal sinuses and nasal cavity account for approximately 4% of head and neck neurilemmomas. In patients with a known history of neurofibromatosis, computed tomography and magnetic resonance imaging can give a clue to this diagnosis, which requires confirmation by histology. This report is of a patient with nasal neurilemmoma and neurofibromatosis 2.
