Cerebral edema is abnormal accumulation of fluid in brain tissue, classified as vasogenic (blood-brain barrier disruption, tumor/infarct), cytotoxic (cellular swelling, hypoxia/ischemia), and interstitial (hydrocephalus). It raises intracranial pressure and can cause herniation. Clinical: headache/vomiting, reduced consciousness, focal deficits. Treatment: head elevation, manage airway/oxygen, osmotic agents (mannitol/hypertonic saline), and treat the underlying cause (tumor/infarct/hydrocephalus/hemorrhage).
