Brain haemorrhage. Illustration of a sectioned human head and brain, seen from the side, showing internal bleeding at the back of the brain. A cerebral bleed can have a number of causes, ranging from a head injury to disorders of the brain's blood vessels. Internal bleeding in the brain is a common cause of a stroke (cerebrovascular accident). In severe cases, the brain may end up damaged due to hypoxia (lack of oxygen).
