Cholesterol Granuloma in the Sphenoid Sinus: A Case Report

The authors report a case of cholesterol granuloma in the sphoid sinus in 54-year old woman, which is probably the first report of cholesterol granuloma arising primarily in the sphenoid sinus apart from the petrous bone. The initial clinical presentations were unilateral decreased visual acuity and facial sensory change. The mass was removed totally via transsphenoidal route and the pathological examination revealed cholesterol clefts and chronic granulomatous changes. The differences between the present case and the previous reports are discussed.
