Résumé : Intrasphenoidal meningoencephalocele is a rare clinical entity. Its origin can be congenital, traumatic, tumoral, or spontaneous. Presenting as cerebrospinal fluid fistula with rhinorrhea, the diagnosis and treatment of this uncommon disease is a real challenge for the otorhinolaryngologist. We report a case of sphenoidal meningocele treated using an endoscopic procedure and review the literature regarding its congenital origin.
