Superficial siderosis of the central nervous system is a rare disorder characterized by the deposition of haemosiderin in the leptomeninges, cranial nerves and spinal cord. The clinical features include sensorineural deafness, ataxia and pyramidal tract signs. We describe two cases demonstrating the characteristic findings on magnetic resonance imaging of widespread peripheral low signal on T2-weighted images.
中枢神经系统表面铁沉积症是一种罕见的疾病，其特征是含铁血黄素沉积于软脑膜、脑神经和脊髓。临床特征包括感音神经性耳聋、共济失调和锥体束征。我们描述了两例病例，展示了磁共振成像上T2加权像广泛外周低信号的特征性表现。
