Abstract

Meningoencephalocele is a rare mass, usually occurring in childhood. This is the herniation of a part of an intracranial component through the skull base defect. Embryologically, the defect result from closure failure of the anterior neuropore. This mass may include meninges (meningocele), meninges and brain (meningoencephalocele), or meninges, brain, and ventricles (meningoencephalocystocele). It is classified as occipital, parietal, basal, and sincipital on the basis of its anatomical location. In past, the treatment of this mass has been by neurosurgeons. The authors experienced a case of basal type intranasal meningoencephalocele in 15 year-old male patient in which the mass protruded into the nasal cavity through the cribriform plate. It was excised successfully by the intranasal approach with nasal endoscopy, and the dural defect was closed by septal cartilage, fascia lata, septal mucosa, and fibrin glue.
