Key Clinical Message: If superficial siderosis is suspected based on clinical presentation, susceptibility weighted imaging should be undertaken in addition to standard MRI sequences as it is more sensitive than T2 weighted imaging. Once diagnosed, imaging of the entire brain and spine must be undertaken to assess for an underlying cause.
