In general, cytotoxic edema is linked to cell death in the brain through excessive cellular swelling. [1] During cerebral ischemia for example, the blood–brain barrier remains intact but decreased blood flow and glucose supply leads to a disruption in cellular metabolism and creation of energy sources, such as adenosine triphosphate (ATP). [1]
An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation, and restrict blood supply to the brain. [13] It is a cause of reflex bradycardia. [14]
High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.
Cerebral Edema that resulted from brain tumor is represented by darker areas on this CT image. An increase in cerebral water content is called cerebral edema and it usually results from traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), subdural hematoma, ischemic stroke, brain tumors, infectious disorders and intracranial surgery.
These changes are observed during routine follow-up magnetic resonance imaging (MRI) scans and involve either brain swelling (edema) or small areas of bleeding due to the rupture of blood vessels ...

Mannitol is used intravenously to reduce acutely raised intracranial pressure until more definitive treatment can be applied, [16] e.g., after head trauma. While mannitol injection is the mainstay for treating high pressure in the skull after a bad brain injury, it is no better than hypertonic saline as a first-line treatment.
