This Sagittal (from the side or lateral) T1 weighted MRI image demonstrates an area of chronic post-traumatic encephalomalacia (brain damage) in a typical location in the anterior inferior frontal lobe. Because the frontal lobe is 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. Also seen is post traumatic atrophy/encephalomalacia of the anterior body of the corpus callosum. | |
