Abstract

Superficial siderosis(SS) of the central nervous system is a rare disease, which is caused by the accumulation of iron from the hemoglobin in the superficial layer of the brain, spinal cord, and central parts of cranial nerves. The etiology of SS is the accumulation of hemosiderin in the subarachnoid space due to chronic or repeated hemorrhage resulting in progressive and irreversible neurological dysfunction. The cause of the disease is aneurysm, trauma, tumor, and vascular malformation. In most cases, the cause of bleeding is unknown. Clinical features include sensorineural hearing loss, cerebellar ataxia, and myelopathy. Until now, MRI has only been diagnosed and there is no standardized treatment. We will investigate clinical features and MRI findings of superficial siderosis disease in the central nervous system using 2 patient cases.
