Spontaneous cerebrospinal rhinorrhea from the sphenoid sinus.

Abstract

A case of spontaneous cerebrospinal rhinorrhea from the sphenoid sinus is presented. Surgical exploration of the sinus revealed a defect of the clivus leading into the posterior fossa. Intrathecal fluorescein dye intraoperatively enabled easy identification of the site. Leakage was stopped by tamponading the sinus, using muscle from the anterior thigh.
