Chronic Post-Traumatic Brain Injury, MRI
This axial (cross sectional) T2 weighted 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, as in this image. There is also enlargement of the temporal horns of the lateral ventricles indicative of chronic atrophy/tissue loss as a result of the brain damage.
