This axial (cross sectional) T2 weighted MRI image demonstrates areas of chronic post-traumatic encephalomalacia (brain damage) in a typical location in the frontal lobes. Because the frontal 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 case. These brighter/whiter regions, partially represent cystic change of the brain due to the brain damage. | |
