A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
High-altitude cerebral edema is a severe and sometimes fatal form of altitude sickness that results from capillary fluid leakage due to the effects of hypoxia on the mitochondria-rich endothelial cells of the blood–brain barrier. [25] The edema can be characterized by vasogenic cerebral edema with symptoms of impaired consciousness and ...
Large numbers of white blood cells enter the CSF, causing inflammation of the meninges and leading to "interstitial" edema (swelling due to fluid between the cells). In addition, the walls of the blood vessels themselves become inflamed (cerebral vasculitis), which leads to decreased blood flow and a third type of edema, "cytotoxic" edema .
In the cadaver, due to the absence of cerebrospinal fluid in the subarachnoid space, the arachnoid mater falls away from the dura mater. It may also be the site of trauma, such as a subdural hematoma, causing abnormal separation of dura and arachnoid mater. Hence, the subdural space is referred to as "potential" or "artificial" space.
A cerebrospinal fluid leak (CSF leak or CSFL) is a medical condition where the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord leaks out of one or more holes or tears in the dura mater. [1]
This can cause severe brain damage by compressing the brain, and a subdural hematoma may develop. Extra-axial fluid collection can be treated in three different ways depending on the severity of the condition. Usually the shunt will be replaced or reprogrammed to release less CSF, and the fluid that has collected around the brain will be drained.
But if fatigue starts to set in, or your leg begins to cramp, a splash of sports drink might be just what you need. Gatorade is the longstanding electrolyte drink that’s fueled athletes for decades.
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. In humans, there is about 125 mL of CSF at any one time ...
