APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Cerebral edema can result from a variety of derangements. The major types include vasogenic, cellular, osmotic, and interstitial. Through these mechanisms, cerebral edema stems from tumor, trauma, hypoxia, infection, metabolic derangements, or acute hypertension.

Detailed explanation-2: -Cerebral edema (CED) is a severe complication of acute ischemic stroke and is the cause of death in 5% of all patients with cerebral infarction. CED is caused by endothelial dysfunction of the capillaries, resulting in breakdown of the blood–brain barrier (BBB).

Detailed explanation-3: -Brain edema is a severe stroke complication that is associated with prolonged hospitalization and poor outcomes. Swollen tissues in the brain compromise cerebral perfusion and may also result in transtentorial herniation.

Detailed explanation-4: -As swelling decreases and blood flow and brain chemistry improve, brain function usually improves. With time, the person’s eyes may open, sleep-wake cycles may begin, and the injured person may follow commands, respond to family members, and speak.
