SUPERFICIAL SIDEROSIS OF THE CENTRAL-NERVOUS-SYSTEM - ITS MRI MANIFESTATIONS

Three cases of superficial siderosis of the central nervous system are reproted here. Using a 1.0-T magnetic resonance (MR) unit, typical hy pointense rims were observed under the brain surface on T2-weighted im ages. In one patient, marked atrophy of the superior cerebellar vermis and cerebellar parenchymal hyperintensity were also detected. The spi nal cord was involved in two of the three patients. On T1-weighted ima ges, hyperintense rims were demonstrated over the brain surface in two of the three patients. This finding has not been previously reported. (C) Elsevier Science Inc., 1997.
