It is an extracellular edema which mainly affects the white matter via leakage of fluid from capillaries. It is most frequently seen around brain tumors both primary and secondary and cerebral abscesses , though some vasogenic edema may be seen around maturing cerebral contusion and cerebral hemorrhage.

Cerebral edema is excess accumulation of fluid edema in the intracellular or extracellular spaces of the brain. Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke , subarachnoid hemorrhage , traumatic brain injury, subdural , epidural , or intracerebral hematoma , hydrocephalus , brain cancer , brain infections, low blood sodium levels , high altitude , and acute liver failure. The treatment of cerebral edema depends on the cause and includes monitoring of the person's airway and intracranial pressure , proper positioning, controlled hyperventilation, medications, fluid management, steroids. As cerebral edema is present with many common cerebral pathologies, the epidemiology of the disease is not easily defined.

The pathophysiological mechanisms following traumatic brain injury. Unitermos: Trauma. Traumatic brain injury is the main cause of death and disability in children and adults in Western Countries. The definitive brain injury is a consequence of pathophysiological mechanisms that begin at the moment of an accident and may extend for days or weeks. Traumatic brain injury may be classified as diffuse or focal. These two mechanisms are commonly associated in a patient, however one is generally predominant. Therefore knowledge of the pathophysiological mechanisms of brain injury in head trauma is important to establish the therapeutic, clinical and surgical measures.
