Cholesterol granuloma is a chronic inflammatory process with associated foreign body reaction to hemorrhage-related cholesterol crystals. In the head and neck region, cholesterol granulomas most frequently occur in the middle ear and mastoid, but they only rarely have been reported in the paranasal sinuses and the frontal bone. Those lesions involving the frontal bone typically occur in the lateral aspect of the supraorbital ridge and more commonly affect men. 1,2 We present a case of a middle-aged woman with a cholesterol granuloma of the medial frontal bone in close proximity to her frontal sinus. The diagnosis and management of this lesion are discussed.
