Another injury classification based on clinical and neuroradiologic evaluation has been proposed. In this classification, TBI would be described as focal or diffuse. Focal injuries include scalp injury, skull fracture, and surface contusions and are generally be caused by contact. Diffuse injuries include DAI, hypoxic-ischemic damage, meningitis, and vascular injury and are usually caused by acceleration-deceleration forces. These 2 forms of injury are commonly found together.
