Document Summary

Tumours are particularly easy to identify on a ct scan as they can influence the function of the brain only by the pressure they exert on surrounding tissue. Gliomas are infiltrating, rapidly growing and unfortunately common. Tumours that don"t originate in the brain they grow from infiltrating cells that are carried to the brain by the bloodstream from some other part of the body. Many metastatic brain tumors originate as cancers of the lungs. The symptoms of a stroke depend on the area of the brain affected but common consequences of stroke are amnesia, aphasia, paralysis and coma. The area of dead or dying tissue produced by a stroke is called infarct. Surrounding the infarct is a dysfunctional area called the penumbra. The tissue in the penumbra may recover or die in the ensuing days, depending on a variety of factors. Bursting aneurysms are a common cause of intracerebral haemorrhage.
