Three cases of superficial siderosis of the central nervous system are reported here. Using a 1.0-T magnetic resonance (MR) unit, typical hypointense rims were observed under the brain surface on T2-weighted images. In one patient, marked atrophy of the superior cerebellar vermis and cerebellar parenchymal hyperintensity were also detected. The spinal cord was involved in two of the three patients. On T1-weighted images, hyperintense rims were demonstrated over the brain surface in two of the three patients. This finding has not been previously reported.
本文报告了3例中枢神经系统浅表性铁沉积症。使用1.0-T磁共振（MR）设备，在T2加权图像上观察到脑表面下典型的低信号边缘。在1例患者中，还检测到小脑上蚓部明显萎缩和小脑实质高信号。3例患者中有2例脊髓受累。在T1加权图像上，3例患者中有2例脑表面出现高信号边缘。这一发现此前未见报道。
