Glial Heterotopia over the Nasal Septum: A Case Report and Review of the Literature

Abstract

ABSTRACT Nasal gliomas are rare congenital lesions arising from defective embryonic development, often termed as Nasal glial heterotopias. It manifests as a mass of extra-cranial cerebral tissue unconnected with the brain. Clinically, these masses are firm and incompressible. Histopathologically, they consist of neuroglial cells and astrocytes embedded in fibrous and vascular connective tissue. Radiological investigations, such as computed tomography (CT) or magnetic resonance imaging (MRI) should be done to rule out intracranial extension. The mass was completely resected endoscopically which was attached to the anterior part of the nasal septum. Endoscopic technique provides excellent visualization. We report one case of nasal glial heterotopia in a baby from southern part of Odisha which has an unusual attachment over the septum. A review of the literatures regarding nasal glioma is also presented. How to cite this article Swain SK, Dash S, Baisakh MR, Samal R.
