Recovery of corticospinal tract with
diffuse axonal injury: A diffusion tensor image study.
Diffuse Axonal Injury Classification Grade Pathology Duration of Coma I Widespread axonal damage in Brief loss of white matter of cerebral consciousness hemispheres II White matter axonal damage Coma of duration; extending to the corpus recovery process callosum with tissue tear unclear hemorrhages III Pathology of Grade II Immediate coma with
diffuse axonal injury posturing and (DAI) with tissue tear incomplete recovery hemorrhages in the brain stem Table 2.

As discussed in pathogenesis the key to management of a head injured patient with cerebral edema or
diffuse axonal injury is to maintain cerebral perfusion pressure by control of ICP and hemodynamic status.
Mechanisms of injury in blunt or closed traumatic brain injury may be primary, including intracerebral hemorrhage, ischemic infarct, contusion, or
diffuse axonal injury; or secondary, producing delayed effects that can include edema, hypoxia, hydrocephalus, increased intracranial pressure, intracranial hemorrhage, or extra or intracranial hematoma.
Primary Brain Injury: Occurs at the time of trauma (Cortical contusions, lacerations, bone fragmentation,
diffuse axonal injury and brain stem contusion).
According to Dolinak and Matshes (23), complex skull fractures usually occur as a result of severe head trauma and are associated with extradural and subarachnoid hemorrhages, cerebral edema, and
diffuse axonal injury, which are additional markers of severe head injury.
She was in a medically induced coma after suffering a fractured skull and
diffuse axonal injury, an injury similar to that suffered by Michael Schumacher in 2013.
Transient lesions in the SCC can be seen in some conditions such as encephalomyelitis, epilepsy, antiepileptic drug toxicity/withdrawal, multiple sclerosis,
diffuse axonal injury, and hypoglisemic encephalopathy.
Then aged 15, he suffered a
diffuse axonal injury - one of the most devastating types of brain trauma.
Then aged just 15, he suffered a
diffuse axonal injury - one of the most devastating types of brain trauma.
by four different mechanisms: 1)
diffuse axonal injury duringacceleration/deceleration, 2) tentorium shear strain at the midbrain as a result of the damage caused by the cutting effect from the rigid nature of the tentorium, 3) injury of the neurovascular structures due to edge of tentorium, and 4) hyperextension of the cervical vertebrae injuringthe lower brain stem (9).
