Objective To explore the diagnosis and treatment methods for temporal bone cholesterol granuloma without chronic otitis media. Methods Patient with surgically confirmed bilateral huge temporal bone cholesterol granuloma were reviewed. Results Cholesterol granulomas presenting MRI with high signal intensity on T 1 and T 2 weighted images, which combined with their lack of enhancement or only mild peripheral enhancement with gadolinium were almost pathognomonic for the disease. Conclusion Magnetic resonance imaging is important for the diagnosis. Surgical cure is achieved by drainage and reestablishment of normal pheumatization.
