Nasal Glioma: A Rare Cause of Congenital Inner Canthal Swelling

Nasal glioma, encephalocele, and ectopic brain are rare congenital anomalies. The terminology applied to these entities has been historically confusing. In many cases, the terms overlap and may be employed synonymously although some authors emphasize their differences. The authors describe herein a child with an inner canthal mass of brain-like tissue that they interpret as nasal glioma, a variety of encephalocele that has lost its connection to the intracranial contents. This research was conducted in conformity with the Helsinki Declaration and Health Insurance Portability and Accountability Act regulations. Accepted for publication January 17, 2018. The authors report no conflicts of interest. The authors alone are responsible for the content. Address correspondence and reprint requests to Norman C.
