MRI showing superficial siderosis. A T2-weighted axial section of brain from MRI (left) and a sagittal T2-weighted section of the cervical spine MRI (right). There is a rim of signal drop-out (hypointensity) surrounding the brainstem, cerebellum and spinal cord (white arrows), consistent with paramagnetic material, in this case haemosiderin, suggesting superficial siderosis.
