Cerebral edema is a potentially life-threatening complication of severely decreased sodium ion concentration in the blood (hyponatremia). [17] Ionic brain edema can also occur around the sites of brain hemorrhages, infarcts, or contusions due to a local plasma osmolality pressure gradient when compared to the high osmolality in the affected tissue.
An intraparenchymal bleed (bottom arrow) with surrounding edema (top arrow) Pediatric stroke is a stroke that occurs in children or adolescents. Stroke affects an estimated 2.5 to 13 per 100,000 children annually. [1] The signs and symptoms of stroke in children, infants, and newborns are different from those in adults.
The symptoms depend on the cause of the blockage, the person's age, and how much brain tissue has been damaged by the swelling. [11] In infants with hydrocephalus, CSF builds up in the central nervous system (CNS), causing the fontanelle (soft spot) to bulge and the head to be larger than
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]
[1] [6] Up to 1% of children with DKA develop a complication known as cerebral edema. [2] Rates of cerebral edema in US children with DKA have risen from 0.4% in 2002 to 0.7% in 2012. [44] Between 2 and 5 out of 10 children who develop brain swelling will die as a result. [10]
SBS is a highly controversial diagnosis. Infants have been shown to suffer some of the "triad" symptoms of SBS—subdural hematoma, retinal hemorrhage, and brain swelling—after short falls or ...
Clinical signs of cerebral edema, such as focal neurological deficits, papilledema [5] and decreased level of consciousness, if temporally associated with recent hemodialysis, suggest the diagnosis. A computed tomography of the head is typically done to rule-out other intracranial causes.
Younger children or infants may present with irritability, poor appetite and fever. [7] Neurological examinations usually reveal a drowsy or confused person. Stiff neck, due to the irritation of the meninges covering the brain, indicates that the patient has either meningitis or meningoencephalitis. [8]
