Cholesterol granuloma cyst of the petrous apex is an uncommon lesion and often presents a diagnostic and management dilemma to the otolaryngologist. Patients usually demonstrate signs and symptoms referable to a mass lesion of the cerebellopontine angle or brainstem. We present two cases of cholesterol granuloma cyst that were treated at our institution and discuss our diagnostic and management algorithms. Also included is a thorough review of the literature.
