Spontaneous cerebrospinal fluid rhinorrhea with associated sinusitis and allergic rhinitis.

Abstract

The entity of spontaneous cerebrospinal fluid rhinorrhea is a rare condition that presents a special challenge to the practicing allergist. Delayed diagnosis can be associated with significant morbidity and mortality. We describe two cases of this condition occurring in association with allergic rhinitis and sinusitis. The presentation and management of these cases is described. A high index of suspicion for this condition should be maintained in all patients who present with profuse and often unilateral rhinorrhea.
