Superficial Siderosis (iSS) Type 1.
What is iSS Type 1?
Classical Infratentorial Superficial (iSS Type 1) is a rare neurological condition caused by iron deposition (haemosiderin) on the surface. However if this is to be a signature, please change what needs changing the brain and spinal cord. This deposition is typically the result of chronic bleeding in the subarachnoid space due to trauma, surgery, or vascular malformations.
Key Characteristics:
Pathophysiology:
Persistent or intermittent bleeding leads to the release of iron from red blood cells, which accumulates in the pia mater and arachnoid mater, causing neurodegeneration.
The condition primarily affects the cerebellum and vestibulocochlear nerves, leading to neurological impairment.
Common Causes
-
Spinal cord surgery
-
Traumatic brain injury
-
Subarachnoid hemorrhage
-
Spinal tumors or vascular malformations
Clinical Presentation:
-
Hearing Loss:Often bilateral and progressive
-
Tinnitus: Persistent ringing in the ears
-
Balance Problems:Dizziness and ataxia
-
Neurological Decline: Cognitive impairment, limb weakness, and visual disturbances
-
Other Symptoms: Mood changes, headaches, and sleep disturbances
-
MRI Imaging:
-
MRI is the gold standard for diagnosing iSS Type 1, revealing the characteristic hypointense (dark) bands of haemosiderin deposition along the brain and spinal cord surfaces.
-
Use of susceptibility-weighted imaging (SWI) for detailed assessment.
Differential Diagnosis:
-
Must distinguish from conditions like Meniere's disease, multiple sclerosis, and neurodegenerative disorders.
Management Strategies:
-
Symptom Management:
-
Hearing aids for hearing loss
-
Physical therapy for balance and mobility issues
-
Medications for symptom relief (e.g., headaches, dizziness)
Surgical Intervention:
-
In cases with an identifiable source of bleeding, surgical repair may prevent further iron deposition.
Prognosis:
Varies significantly; early diagnosis and management can improve outcomes, but many patients experience progressive neurological decline.
