【Abstracts 】ObjectiveToexplore the diagnosis and surgical treament methods for petrous apex cholesterol granulomas. Methods Six patients with surgically confirmed petrous apex cholesterolgranuloma were reviewed retrospectively.Results Four mature cholesterol granulomasdemonstrated high signal intensities on both T₁ -and T₂ -weightedimages, which, when combined with their lack of enhancement or only meager peripheralenhancement with gadolinium, were almost pathognomonic for this entity. All six patientsunderwent complete removal of the granuloma and cyst wall followed by oblity with apedicled strip of temporalis muscle or fat fragments. No recurrences were seen at a meanfollow-up period of 2 years.Conclusions The concealed characteristics of petrous apexcholesterol granuloma required more careful and detailed clinical and imagingexaminations. The extended subtemporal approach is helpful for radical resection of thelesion.
