Cerebral hemorrhage
(重定向自Intracerebral hemorrhage)
A cerebral hemorrhage (also spelled haemorrhage) is a type of intracranial hemorrhage that occurs within the brain tissue. 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.
