What causes hemosiderin in the brain?
Hemosiderin deposition in the brain is seen after bleeds from any source, including chronic subdural hemorrhage, cerebral arteriovenous malformations, cavernous hemangiomata. Hemosiderin collects in the skin and is slowly removed after bruising; hemosiderin may remain in some conditions such as stasis dermatitis.
What is superficial siderosis of the central nervous system?
Superficial siderosis (SS) of the central nervous system (CNS) is a chronic condition consisting of hemosiderin deposition in the subpial layers of the brain (and spinal cord) due to chronic or intermittent low-grade extravasation of blood into the subarachnoid space.
What is the life expectancy of someone with superficial siderosis?
Severe medical condition with expected life expectancy <3. years….Superficial Siderosis in Patients With Suspected Cerebral Amyloid Angiopathy (SuSPect-CAA)

How is superficial Siderosis treated?
Treatment of SS involves identification and surgical correction of the bleeding source. Deferiprone, which is a lipid-soluble iron chelator that can penetrate the blood-brain barrier, is reportedly effective at improving the clinical symptoms and deposition of hemosiderin. It is thus a hopeful treatment option for SS.
What is hemosiderin in the brain?
Hemosiderin is the deposition of iron particles in the brain parenchyma that signifies an old bleeding site.
Is hemosiderin serious?
Though it can appear anywhere, it’s more prevalent on the lower legs. In many cases, hemosiderin staining can be permanent. The staining alone isn’t life-threatening, but it can be an indication of a more serious condition.
How is superficial siderosis diagnosed?
Diagnosis. Early detection of superficial siderosis is usually via MRI. The iron deposition that is characteristic of superficial siderosis shows up as a hypointense band in affected tissues, with a characteristic rim of intensity appearing on the cerebellum; a hyperintense rim is rarely seen.
What is Hemosiderin deposition?
Hemosiderin — a protein compound that stores iron in your tissues — can accumulate under your skin. As a result, you may notice yellow, brown, or black staining or a bruiselike appearance. Stains most often appear on the lower leg, sometimes covering the space between your knee and ankle.
What are the symptoms of Siderosis?
Patients will present with one or more of the classic triad of symptoms: hearing loss, movement abnormalities (ataxia), and motor difficulties due to suspected spinal cord injury (myelopathy) with pyramidal signs. Proper recognition and timely early diagnosis of superficial siderosis allow for early care planning.
When is hemosiderin formed?
When red blood cells break down, the hemoglobin releases iron. The trapped iron is then stored as hemosiderin in tissues beneath your skin, causing visible hemosiderin staining.
Is superficial Siderosis fatal?
The symptoms and signs of SS are progressive and fatal. Exploration of potential sites responsible for intrathecal bleeding and subsequent hemosiderin deposition may prevent disease progression.
How common is superficial Siderosis?
Superficial siderosis of the central nervous system is a rare condition caused by hemosiderin deposits in the subpial layers of the brain and spinal cord.
