This exam was requested for follow up of some subtle T2/FLAIR signal abnormalities in the white matter in both temporal lobes. This protocol using SWI susceptibility sequences spotted hemosiderin staining within these areas and also in the area of abnormal thinning of the body of corpus callosum. In the setting of a head trauma, as was reported in clinical history, these lesions most likely represent traumatic brain sequelae.

This is one of the reasons why susceptibility sequences should be added in MRI trauma protocols.
