AbstractSuperficial siderosis of the central nervous system is produced by the deposit of hemosiderin within the subpial layers of the central nervous system and central parts of the cranial nerves, leading to progressive degeneration. We report a 55-year-old male who consulted for hearing loss and long-standing progressive decrease in visual acuity, associated with sudden onset of left hemiparesis. A brain CAT scan showed subacute ischemic lesions in the territory of the right posterior cerebral artery (thalamus and right subcortical temporal regions), old ischemic lesions in the right subcortical occipital regions and cerebellar atrophy. A magnetic resonance confirmed the lesions and the presence of superficial diffuse siderosis. A cerebrospinal fluid analysis showed slight xanthochromia, 26 leukocytes/mm3, glucose 51 mg/dL and proteins 1.23 g/L. He was managed with aspirin in low doses and statins. His motor function improved and was discharged two weeks after admission.
