This axial (cross sectional) T2 weighted FLAIR (fluid attenuated inversion recovery) image demonstrates areas of chronic post-traumatic encephalomalacia (brain damage) in a typical location in the temporal lobes (indicated by the red arrows). Because the temporal lobes are so close to the adjacent bony skull base the brain hits the bone during the injury and then over time becomes atrophic and gliotic (brains response to injury). In the chronic phase the area of injury on MRI shows lower (looks darker) signal on T1 and higher (brighter or whiter) signal on T2 weighted images. The darker areas in both temporal lobes represent cystic changes of brain damage and other dark regions in the temporal lobes represent enlargement of the temporal horns of both lateral ventricles indicative of chronic loss of brain tissue from the brain damage. | |
