Nasal Glioma

Abstract

Nasal gliomas are benign congenital midline tumors with the potential for intracranial extension. They are most commonly seen in neonates and children but rarely in adults. The treatment of choice is surgical excision. Inadequate primary excision results in a 4 to 10 percent recurrence. Hence, a thorough preoperative evaluation is essential to delineate the exact site and extension of the tumor and to plan the appropriate surgical approach. Computerized tomographic (CT) scans are useful in visualizing bony defects, but are not well suited for soft tissue imaging. Magnetic resonance imaging (MRI) offers superior soft tissue contrast, without ionizing radiation. This is a report of a neonate with unexplained early respiratory distress. On day 5, a soft nasal mass became apparent. CT scans were inconclusive, so MRI scan was used to demonstrate intracranial extension. MRI is superior for imaging brain tissue, so it should be used preferentially to delineate intracranial extension and to help guide the surgical approach.

“…8 Complete excision of the mass is the treatment of choice and inadequate resection may cause recurrence in 4-10% of cases. 9 Intranasal lesions resection by a transnasal endoscopic approach is the treatment of choice. Extranasal glial heterotopias can be treated by external rhinoplasty approach, or by lateral or medial rhinotomy.…”
