[Spontaneous rhinorrhea of a rare etiology (apropos of empty sella turcica)].

The authors report a case of non traumatic rhinorrhea due to an empty sella turcica. Such an intra sellar arachnoidocele compress the pituitary gland against the posterior wall, erode the floor and lead to CSF rhinorrhea through the sphenoidal sinus. Diagnosis and treatment are best accomplished by a team approach involving otolaryngologist, neurosurgeon and neuroradiologist. CT Scan and IRM explain the diagnosis. Treatment can be accomplished by a transeptal transphenoidal approach with localization and repair of the leak in the absence of increased intracranial pressure.
