[Hearing loss and gait ataxia without dizziness. Hemosiderosis].

Superficial cerebral hemosiderosis is characterized by sensorineural hearing loss, gait ataxia and pyramidal signs with irreversible myelopathy. It is caused by chronic hemorrhage into the subarachnoid space with hemosiderin deposition in the subpial, leptomeningeal and subependymal layers. Imaging of the entire neuroaxis is indicated to localize a source of bleeding, including cerebral and spinal angiography when necessary. Taking into account clinical signs and symptoms the interpretation of T2*-weighted images allows the radiologist to set the course for the optimal therapeutic regimen.
