This is a case report of the successful treatment of a petrous apex cholesterol granuloma through a middle fossa approach, with a comparative analysis of the various approaches. It underlines the advantages of the former approach compared with alternative drainage procedures. The authors choose to obliterate the cavity with fat. Contemporary fat-suppression techniques easily identify fat on magnetic resonance imaging, but fat does create a bright hyperintense signal that could mimic features of a cholesterol granuloma on T1-weighted imaging. We prefer to obliterate the cavity with muscle.[1]
