A cerebral hemorrhage (also spelled haemorrhage; also known as a cerebral hematoma) is a type of intracranial hemorrhage (intracranial hematoma) that occurs within the brain tissue. It is alternatively called intracerebral hemorrhage. It can be caused by brain trauma, or it can occur spontaneously in hemorrhagic stroke. Non-traumatic intracerebral hemorrhage is a spontaneous bleeding into the brain tissue and may be caused by increased exertion, tension or stress.
