Abstract
BACKGROUND: Nasal glial heterotopias (NGHs) are benign lesions diagnosed at birth that are treated with complete surgical excision and have a low recurrence rate. The impact of the timing of resection on the patients' outcome remains unclear. CASE DESCRIPTION: We report a case of pediatric midline subcutaneous extranasal glial heterotopia over the nasal bridge in a 4-day-old female newborn. At the age of 6 months, she underwent a complete surgical excision. Follow-up magnetic resonance imaging at 3 years showed no evidence of recurrence. A summary of the 19 published cases of the specific entity of purely subcutaneous extranasal glial heterotopia among the pediatrics age group in the literature is presented, and the timing of surgery in relation to outcome is discussed. CONCLUSION: Our review revealed that surgery for NGH can be safely performed when the child is 6-12 months old, and the child should be followed probably until school age.
