Intranasal meningoencephalocele is a rarely encountered congenital malformation. We report a case of transethmoidal intranasal meningoencephalocele in a 52-year old man with recurrent purulent meningitis. After treatment of the acute meningitis, frontal craniotomy followed by the removal of the stalk of the meningoencephalocele and repair of the bony defect was successfully performed. He has had no further meningitis or CSF rhinorrhea post-operatively. Detailed neuroradiological examination and appropriate surgical treatment are important to prevent fatal neurological complications of intranasal meningoencephalocele.
