Abstract

Isolated sphenoid sinus disease is often misdiagnosed because of its rarity and varing clinical presentation. A 51-year-old male visited the hospital with abnormal brain CT findings which showed homogenous opacification associated with sinus wall expansion on the right sphenoid sinus. Under the impression of isolated sphenoid mucocele, the fenestration of sphenoid sinus was conducted without surgical complication. But, cerebrospinal fluid rhinorrhea spontaneously developed 3 days after fenestration operation and then stopped by sealing the suspicious leakage 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 developed in sphenoid sinus.
