Microglia and Bergmann cells in the cerebellum produce ferritin to counteract any rise in the harmful CSF free iron levels.,, In cases where repeated subarachnoid microbleeds occur, beyond the capacity of the Bergmann cells, iron is released from ferritin due to oxidative stresses.,, Superficial cortical layers and structures exposed in the cisternal space get permanently destroyed by free radical damage and lipid peroxidation catalyzed by free iron.,, Common sites of injury in superficial cerebral hemosiderosis (SCH) include the cerebellum and the vestibulocochlear nerve.,, Patients usually present with gradually progressive hearing loss with gait ataxia and a distinctive pattern of socio-cognitive decline.,
Early identification and removal of the inciting factor are essential., Role of chelating factors is not proven. Once damage to the cortex is done, eradication of the underlying cause will not reverse the clinical deficits due to SCH. It is also not clear whether removing the source of bleed will halt the progression of the damage. Guarded prognosis needs to be explained prior to surgical intervention in such cases. Cognitive dysfunction, gait ataxia, and vestibulocochlear symptoms are not expected to improve even when the patient recovers from the primary condition (such as a bled intracranial neoplasm or vascular abnormality) without any deficits.
A 49-year-old male patient, with history of repeated episodes of moderate to severe holocranial headache associated with vomiting for past seven years, had presented with gait disturbance of 1-year duration and behavioral disturbance for past one week. The patient was disoriented in time and person, significant cognitive dysfunction with bilateral cerebellar signs and gait ataxia. The clinico-radiological picture was suggestive of SCH [Figure 1], [Figure 2], [Figure 3]. Histopathology of the inciting lesion was Astrocytoma Grade III.
