초록

Isolated sphenoid sinus disease is often misdiagnosed because of its rarity and varing clinicalpresentation. A 51-year-old male visited the hospital with abnormal brain CT findings whichshowed homogenous opacification associated with sinus wall expansion on the right sphenoidsinus. Under the impression of isolated sphenoid mucocele, the fenestration of sphenoid sinuswas conducted without surgical complication. But, cerebrospinal fluid rhinorrhea spontaneouslydeveloped 3 days after fenestration operation and then stopped by sealing the suspiciousleakage site with free graft of inferior turbinate mucosa. Based on the pathological findings,paranasal sinus CT and MRI findings, this case is reported to be meningoencephalocele developedin sphenoid sinus.
