The Monroe–Kellie doctrine states that the skull is a fixed and inelastic space and the accumulation of edema will compress vital brain tissue and blood vessels. [8] [38] Surgical treatment of cerebral edema in the context of cerebellar or cerebral infarction is typically done by removing part of the skull to allow expansion of the dura. [38]
The diagnosis is usually made by a brain scan , in which areas of swelling can be identified. The treatment for PRES is supportive: removal of the cause or causes and treatment of any of the complications, such as anticonvulsants for seizures. PRES may be complicated by intracranial hemorrhage, but this is relatively rare. The majority of ...
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.
Brain injury will commonly be accompanied by acute swelling, which impairs function in brain tissue that remains alive. Resolution of swelling is an important factor for the individual's function to improve. The greatest factor in functional recovery after brain injury comes from the brain's ability to learn, called neuroplasticity. After ...
Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull. The brain can shift across such structures as the falx cerebri , the tentorium cerebelli , and even through the foramen magnum (the hole in the base of the skull through ...
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]
Lee's death was officially ruled the result of cerebral edema — swelling of the brain. While a normal human brain is about 3 pounds, Lee's was reportedly closer to 3½ pounds.
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.
