Cholesterol granulomas arise scarcely within the middle ear cavities revealed by a conductive deafness. They appear on the CT scan as a non specific mass developed in the middle ear cavities with bone defects. MRI allow the diagnosis as cholesterol granulomas is defined by hyperintensity on all sequences.
胆固醇肉芽肿很少出现在因传导性耳聋而显影的中耳腔内。它们在CT扫描上表现为中耳腔内出现的伴有骨质缺损的非特异性肿块。磁共振成像（MRI）能够做出胆固醇肉芽肿的诊断，因为在所有序列上它都表现为高信号。
