The authors present a case of a Diffuse Axonal Injury DAI that is evident on MRI, though not on CT. In this full-text version we present two more cases of parenchymal injury in increasing severity. There is a continual clinical and imaging spectrum of severity of head trauma from seemingly trivial falls or car accidents to blast exposure at various distances, to high velocity penetrating and perforating ballistics. Mild Traumatic Brain Injury mTBI, has received significant publicity in current military operations. Our case illustrates one of the more subtle findings on imaging, followed by more severe cases with more extensive findings. We present companion closed head injury cases of increasing severity of parenchymal damage to pictorially outline the imaging spectrum, then introduce penetrating trauma and a standard report with hopes to further set the future imaging perspective.
