Intranasal glial heterotopia in a male infant: A case report.

ABSTRACT

RATIONALE Nasal glial heterotopia is a rare type of neoplasm consisting of meningothelial and/or neuroglial elements. PATIENT CONCERNS A 2-month-old male was evaluated for treatment of a congenital mass in the right nasal cavity near the pharynx. DIAGNOSES The patient was preoperatively diagnosed with a congenital intranasal neoplasm. INTERVENTIONS: Nasal endoscopic resection of the nasopharyngeal mass was performed under general anesthesia. Histological examination of the resected tissue provided a diagnosis of intranasal glial heterotopia. OUTCOMES: The surgical outcome was good, with no surgical site infection. After 1 year of follow-up, the boy was asymptomatic with no recurrence. LESSONS Excision of a nasopharyngeal mass via nasal endoscopy resulted in no recurrence during 1 year of follow-up. Before any surgical treatment for suspected glial heterotopia, the mass should be differentiated clinically and radiologically from an encephalocele to prevent the risk of cerebrospinal fluid leakage and meningitis.
