  • Abstract
  • Look Inside

A 51-year-old female complained of right ear-ache. MRI and CT scans revealed a large cystic lesion in the mastoid, the middle and posterior cra-nial fossa. Surgery through a postauricular incison disclosed a large cholesterol cyst that contained brownish fluid. Near the mastoid tip, the cyst had a thick granulomatous outer wall, which showed characteristic histopathological findings as choles-terol granuloma. The thickened wall was resected and the large cavity was opened into the external auditory canal. The literature was reviewed and operation methods for this disease were discussed.
