    Dear Colleagues

    Concerning “superficial siderosis” I would like to emphasize that we have to distinguish two different types regarding localization and pathophysiology: 1) The infratentorial type that was described in the case report [1]. Patients present with a triad of sensorineural hearing loss, ataxia and myelopathy [2]. Treatment is based on staunching recurrent bleeding and elimination of toxic iron deposits with deferiprone. The latter is not without some risk: neutropenia with sepsis [3]. – 2) The supratentorial type is a manifestation of cerebral amyloid angiopathy in the vast majority of cases [4], and there is no known cure. Cortical superficial siderosis – of the supratentorial type – is the cause of transient focal neurological episodes that can mimic transient ischaemic attacks, migraine auras or simple partial seizures [5].

    Yours sincerely,
