title: Superficial siderosis: a case report.
abstract: Superficial siderosis of the central nervous system is the result of chronic recurrent hemorrhages (e.g., arteriovenous malformations, tumors, or trauma), which leads to the accumulation of cytotoxic hemosiderin and presents with hearing loss, cerebellar dysfunction, and myelopathy. This article presents a clinical case of an 11-year-old boy in whom the diagnosis of medulloblastoma was established. He underwent surgery, and after a few years, he began to complain of hearing loss. Magnetic resonance imaging revealed the cause of the hearing disturbance. The aim of this article is to review the recent literature related to the etiology, clinical and radiologic features of superficial siderosis, emphasizing the role of magnetic resonance imaging.
