Superficial Siderosis of the Spine MRI Findings
What is it?
Superficial siderosis is due to the chronic deposition of hemosiderin in the subpial layer of the brain and spine.
Why does it occur?
Its due to chronic, low grade bleeding and only uncommonly due to an acute subarachnoid hemorrhage. The cause can be difficult to determine but often patients have had trauma or trans dural surgery with resultant chronic low grade bleeding from those sites. Vascular malformations and rarely patients on long term warfrin with poor control can result in superficial siderosis. There is also an association with spinal epidural cysts whci are thought to result from a tear in the dura.
