Front Back
Tumor; Neoplasm
"New growth," a mass of cells that grows independently of the rest of the body.
Meningiomas
Tumors that grow between the meninges, the three membranes that cover the central nervous system
Encapsulated tumors
Tumors that grow within their own membrane (i.e., meningiomas)
Benign tumors
Tumors that are surgically removable with little risk of further growth in the body
Infiltrating tumors
Those that grow diffusely through surrounding tissue
Malignant tumors
It is difficult to remove or destroy them completely, and any cancerous tissue that remains after surgery continues to grow.
Metastatic tumors
Tumors that do not originate in the brain, but instead are infiltrating tumor fragments carried to the brain by the bloodstream from some other part of the body. Metastasis is the transmission of disease from one organ to another.
Strokes
Sudden-onset cerebrovascular disorders that cause brain damage.
Penumbra
Area of dysfunctional tissue surrounding the infarct.
Cerebral hemorrhage
Bleeding in the brain; occurs when a cerebral blood vessel ruptures and blood seeps into the surround structure and damages it.
Aneurysm
A pathological balloonlike dilation that forms in the wall of an artery at a point where the elasticity of the artery wall is defective. Aneurysms can occur in any part of the body and can be congenital (present at birth) or can result from exposure to vascular poisons or infection.
Cerebral ischemia
A disruption of the blood supply to an area of the brain.
Thrombosis
When a plug called a thrombus is formed and blocks blood flow at the site of its formation.
Embolism
Similar to thrombosis, except that the plug called an embolus in this case, is carried by the blood from a larger vessel, where it is formed, to a smaller one, where it becomes lodged (a thrombus that has taken a trip).
Ateriosclerosis
When the walls of blood vessels thicken and the channels narrow, usually as the result of fat deposits; this narrowing can eventually lead to complete blockage of blood vessels.
