Extracranial meningiomas are rare tumors that usually represent extensions from intracranial lesions. Here, we report a case of primary meningioma of the nasal septum. A 60-year-old man presented with nasal obstruction and postnasal drip. On examination he had a mass in the nasal cavity. Computed tomography studies revealed absence of intracranial extensions. The mass was successfully excised and the histologic diagnosis of meningioma was established. This report documents what we believe to be the first case (in English medical literature) of an extracranial meningioma, involving the nasal septum. The clinicopathologic features and pathogenesis of the primary nasal meningioma is briefly discussed.

Rhinitis is characterized by rhinorrhea, sneezing, nasal congestion, nasal itch and/or postnasal drip. Often the first step in arriving at a diagnosis is to exclude or diagnose sensitivity to inhalant allergens. Non-allergic rhinitis (NAR) comprises multiple distinct conditions that may even co-exist with allergic rhinitis (AR). They may differ in their presentation and treatment. As well, the pathogenesis of NAR is not clearly elucidated and likely varied. There are many conditions that can have similar presentations to NAR or AR, including nasal polyps, anatomical/mechanical factors, autoimmune diseases, metabolic conditions, genetic conditions and immunodeficiency. Here we present a case of a rare condition initially diagnosed and treated as typical allergic rhinitis vs. vasomotor rhinitis, but found to be something much more serious. This case illustrates the importance of maintaining an appropriate differential diagnosis for a complaint routinely seen as mundane. The case presentation is followed by a review of the potential causes and pathogenesis of NAR.
