Abstract

Superficial siderosis results from the deposition of hemosiderin in subpial layers of the central nervous system following hemorrhage in subarachnoid spaces. Infratentorial superficial siderosis (ISS) presents with unique clinical features including progressive hearing loss, ataxia, and myelopathy, and the most common cause of idiopathic ISS is dural abnormality. Here we report a case of idiopathic ISS with radiological findings of spontaneous intracranial hypotension, whose clinical symptoms of ISS including cerebellar dysfunction improved after supine position was maintained for 2 months.
