Diffuse axonal injury in a 14-year-old boy who had severe TBI following a motorcycle crash. Brain MR study was performed three days after the trauma, when the patient was in a severely comatose state (GCS 5). a FLAIR image identifies multiple hyperintense lesions in the splenium of the corpus callosum and in frontal subcortical and periventricular white matter. b GE T2*-weighted image: haemorrhagic shearing injuries are barely visible in the right fronto-opercular and parieto-occipital regions (arrows). c SWI minIP: additional microhaemorrhages are recognisable at the grey matter-white matter junction of the frontal lobes and in the right parieto-occipital white matter (black arrows). d SWI minIP, reformatted sagittal section shows microhaemorrhages in the corpus callosum (white arrows)
