Stroke. Gross specimen and computed tomography (CT) scan of an intracerebral haematoma (black and bright orange respectively), or blood clot, in the right cerebral hemisphere. This sort of blood clot, which is often fatal, is caused by blood vessels in the brain haemorrhaging. This haemorrhage was due to high blood pressure, but other causes are injury or an abnormality of the blood vessels. The pressure exerted on the brain by the blood can give a number of symptoms, depending upon which area is affected. The symptoms can include headache, nausea, changes in vision and loss of balance. Treatment is with surgery to remove the clot.
