Primary Atypical Meningioma of the Nasal Cavity: A Case Report and Review of the Literature

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: Meningioma is a central nervous system tumor that typically arises in proximity to meninges. Extracranial primary atypical meningioma of sinonasal tract is a rare one. METHODS: We discuss the clinical, radiological, and histological presentation of an elderly female with primary atypical meningioma of the nasal cavity, which was excised via endoscopic endonasal approach. RESULTS: There was no recurrence even up to 20 months of follow-up after endoscopic excision. CONCLUSION: Extracranial primary atypical meningioma should be kept in mind as one of the differential diagnoses of nasal mass. Histopathological diagnosis along with immunohistochemistry should be used for definitive diagnosis.
