Different etiologies of superficial siderosis

Superficial Siderosis (SS) is an uncommon condition caused by hemosiderin deposition into the subarachnoid space. SS is characterized by cerebellar ataxia, progressive sensorineural hearing loss and pyramidal signs, but is often an unrecognized disorder. Magnetic Resonance Imaging (MRI) is the diagnostic procedure of choice due its high sensitivity to hemosiderin deposits in addition to being a non-invasive exam. This paper aims to describe a case of SS and to perform a literature review about SS etiologies, neuroimaging features and clinical characteristics. A 65-year-old man came to a neurology outpatient clinic with seizures and cerebellar ataxia with a history of car accident and severe traumatic brain injury 45 years ago. MRI SWAN showed a hyposignal in the cisterns of the base and on the cerebellar surface and T1-weighted images left hippocampal sclerosis.
