Primary Ectopic Meningioma of Nasal Cavity: A Rare Presentation

Primary ectopic meningiomas of the nasal cavity are rare tumours and thus, often not diagnosed and treated properly. In this case report we are going to discuss about our experience with a primary nasal meningioma involving bilateral nasal cavity with its diagnosis, management and histopathological features. A 28 year old female presented with nasal obstruction and nasal discharge for the past 1 year and swelling over right side of face for the past 8 months. Patient underwent surgical resection by a combined endoscopic and external approach under general anaesthesia. Histopathological evaluation confirmed the diagnosis of Transitional meningioma WHO grade 1. A repeat nasal endoscopy done one week after surgery, showed no evidence of any residual tumour. Due to ectopic meningiomas being relatively less common one must always exclude the presence of a central meningioma, which makes radiological investigations a must in such cases. As primary extra-cranial meningiomas have an unpredictable behaviour, this study should further aid in diagnosis and management of these tumours.
