INTRODUCTION: Nasal meningocele, which is usually congenital, is a rare anomaly resulting from meningeal herniation into the nasal cavities through a bone defect in the skull base. CASE REPORT: An 8-day-old boy was referred with respiratory disturbance and nasal obstruction. Examination showed a cyst-like grayish swelling filling the right nasal cavity. CT scan showed opacity, of fluid-like density, filling the right nasal fossa, in contact with a small bony defect in the right cribriform plate. MRI ruled out herniated brain parenchyma and enabled diagnosis of meningocele. The patient was operated on at the age of 2 months through a transnasal endoscopic approach. Immediate postoperative course was favorable. MRI control at 8 months was normal. DISCUSSION: Modern imaging (CT scan and MRI) is of paramount importance in the preoperative evaluation of nasal meningocele. Endoscopic endonasal (EE) surgery is currently the treatment of choice. CONCLUSION: Steady progress in instrumentation, technique and skills will increase the feasibility of skull-base surgery using an endonasal approach in the pediatric population.
