Cholesterol granuloma is a histopathological diagnosis with features of cholesterol clefts, foreign body giant cells, and macrophages filled with hemosiderin. It is commonly found in the mastoid or petrous apex, but the involvement of paranasal sinuses is very rare. Radiologically, cholesterol granuloma show typical findings of hyperintense signals on both T1- and T2-weighted images on magnetic resonance imaging (MRI). We report two cases of cholesterol granuloma in the sphenoid sinus, which were first misinterpreted as mucoceles due to unusual MRI images
