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

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.
