SUPERFICIAL SIDEROSIS OF THE CENTRAL-NERVOUS-SYSTEM - DIAGNOSIS BY MAGNETIC-RESONANCE-IMAGING

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 sensori neural deafness, ataxia and pyramidal tract signs. We describe two cas es demonstrating the characteristic findings on magnetic resonance ima ging of widespread peripheral low signal on T2-weighted images.
