ABSTRACT: Objective: This paper reports a rare case of nasal glial heterotopia presenting as sphenochoanal polyp. So far, literature has revealed only few cases. Case Report: A 55-year-old woman presented with a 2-month history of left sided nasal obstruction. Rigid endoscopy showed greyish left nasal polyp and anterior discharge. Subsequently, CT scan of the sinuses revealed sphenochoanal polyp filling the left nasal cavity, without signs of expansion, or destruction and no obvious connection with intracranial tissue. Mass was removed endoscopically and histology confirmed glial nature of the mass. Conclusion: Any mass arising from sphenoid sinus should be carefully evaluated on CT scan for existence of fibrous stalk, or connection with brain tissue and needs to be considered in the differential diagnosis of the sphenochoanal mass. Complete surgical excision is the treatment of choice, which is curative.
