A Case Report of Nasal Glial Heterotopia

Abstract

Nasal glial heterotopia (NGH), also known as nasal glioma, is a rare congenital malformation in which a mature glial cell mass is found in a location other than the central nervous system. These benign masses are divided into 3groups based on localization: the intranasal, extranasal, and mixed types. Here we present a case study of a young boy with an extranasal-located NGH who underwent surgical resection. Radiological examination is indispensable to differentiate between other midline masses (hemangiomas, dermoid cysts, and encephaloceles). Magnetic resonance imaging should exclude communication with the central nervous system. Computed tomography is used to verify the integrity of the anterior skull base. The proper management of NGH is a complete resection, often by a multidisciplinary approach involving otorhinolaryngology, neurosurgery, and reconstructive surgery.
