Diffuse axonal injury (DAI) is a frequent result of traumatic deceleration injuries and a frequent cause of persistent vegetative state in patients. DAI is the most significant cause of morbidity in patients with traumatic brain injuries, which most commonly are the result of high-speed motor vehicle accidents. Typically, the process is diffuse and bilateral, involving the lobar white matter at the gray-white matter interface. The corpus callosum frequently is involved, as is the dorsolateral rostral brainstem. The most commonly involved area is the frontal and temporal white matter, followed by the posterior body and splenium of the corpus callosum, the caudate nuclei, thalamus, tegmentum, and internal capsule.
