ECM Why would cause increased intracranial pressure?

ECM bacteria penetrated meninges, Yields in the meningeal large-min, meningococcus and endotoxin stimulate meninges, the arachnoid and leptomeningeal inflammation. In addition to the inflammatory lesions meninges, the substance of the brain and spinal cord may also have inflammation, which occurred vascular congestion, leukocyte infiltration, brain cell degeneration and necrosis, and other changes. Also due to hypoxic brain tissue caused cerebral edema, brain tissue volume than the original increase, weight also increased, serious than the normal 50%. Brain hard in the first skull, it can increase the size slightly increased intracranial pressure caused because the capacity is fixed. The skull, including brain tissue, blood vessels and blood, cerebrospinal fluid of three parts; cerebral edema, brain weight and increased the capacity to make increased intracranial pressure, which is caused intracranial hypertension ECM reasons.
