Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations .
Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.
Cerebral spinal fluid lymphocytic pleocytosis is generally the result of an immune response to neurovascular inflammation. Many cases point to a viral infection as the root cause of pleocytosis, in which the immune system produces antibodies against neuronal and vascular antigens .
The blood–brain barrier becomes more permeable, leading to "vasogenic" cerebral edema (swelling of the brain due to fluid leakage from blood vessels). 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).
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.
Viral meningitis, also known as aseptic meningitis, is a type of meningitis due to a viral infection. It results in inflammation of the meninges (the membranes covering the brain and spinal cord). Symptoms commonly include headache, fever, sensitivity to light and neck stiffness. [1] Viruses are the most common cause of aseptic meningitis.
Cerebrospinal fluid rhinorrhoea; Specialty: Neurology, neurosurgery, otorhinolaryngology,Oral and maxillofacial surgery: Symptoms: clear, colourless liquid draining from nose: Complications: infection: Causes: basilar skull fracture: Diagnostic method: brain scans, testing nasal discharge to see if it is CSF: Differential diagnosis: other types ...
Ventriculitis, also known as ependymitis, ventricular empyema, pyocephalus, and pyogenic ventriculitis, [1] [2] is the inflammation of the ventricles in the brain. The ventricles are responsible for containing and circulating cerebrospinal fluid throughout the brain.
