OBJECTIVE: To investigate the pathophysiological mechanism, clinical menifestation and radiographic diagnosis of cholesterol granuloma following chronic suppurative otitis media.
METHOD: Six cases of CG following chronic suppurative otitis media, confirmed by surgery and pathology, were reviewed and analyzed.
RESULT: CG frequently accompanied with other middle ear diseases, and was shown as a high signal intensity on both T1-and T2-weighted images in magnetic resonance imaging(MRI).
CONCLUSION: It was postulated that the obstruction of pneumatized temporal bone air cell, caused by other middle ear diseases such as cholesteatoma and tympanosclerosis, might be the pathophysiological mechanism of CG. The evaluations of computed tomography (CT) and clinical manifestation were limited to distinguish CG from cholesteatoma or other neoplasm, while the MRI can be of great value to characteristic diagnosis.
