We present a 50-year-old man who was investigated for sensorineural hearing loss. On MRI of the brain superficial siderosis of the central nervous system was seen, while MRI of the spine revealed an ependymoma of the cauda equina. This case illustrates the importance of performing T2-weighted imaging of the brain and posterior fossa when sensorineural hearing loss is present. Spine imaging is mandatory when superficial siderosis of the brain is diagnosed without identification of a bleeding source in the brain.
我们报告一名50岁男性，因感音神经性听力损失接受检查。脑部MRI显示中枢神经系统存在浅表性铁沉积症，而脊柱MRI显示马尾神经有室管膜瘤。该病例说明了当存在感音神经性听力损失时，对脑部和后颅窝进行T2加权成像的重要性。当诊断为脑部浅表性铁沉积症而未发现脑部出血源时，脊柱成像必不可少。
