False-colour computer processed image of a gross specimen of a brain showing the site of an intracerebral haemorrhage (dark, centre left). Brain haemorrhages occur either after a head injury or are caused by the spontaneous rupture of blood vessels. They are divided into four main categories - extradural, subdural, subarachnoid and intracerebral haemorrhages - according to the site of the bleeding. The first three involve bleeding between the skull and the meninges, the membranes which cover the brain. Intracerebral haemorrhages occur within the brain and are usually caused by the spontaneous rupture of blood vessels.
