Abstract

Meningoencephalocele is an ectopic protrusion of the meninges and a portion of the brain that retains connection with the CNS through a defect in the bony covering. It is a rare developmental anomaly that results from faulty closure of the embryonic neural tubes. Meningoencephalocele is usually classified into occipital, sincipital and basal types according to the location and among these, the basal type is less frequently encountered than other types. The authors have experienced a case of basal-type intranasal meningoencephalocele in 4 year-old male patient, which was removed successfully via bifrontal craniotomy and intranasal endoscopic approach, and the defect of skull base was repaired by inner table of the cranium and septal mucosa with good result.
