The difference between cerebral hemorrhage and cerebral hemorrhage, cerebral hemorrhage refers to bleeding in the brain parenchyma or ventricular system or subarachnoid space due to various reasons, such as cerebral arteriosclerosis caused by traumatic brain injury, hypertension, diabetes mellitus, arteriovenous fistulae, arteriovenous malformation, cerebral aneurysm rupture and other cerebral hemorrhage, the blood flows into the brain parenchyma or subarachnoid space or the surface of the brain and the corresponding clinical symptoms caused by the blood flow. Cerebral hemorrhage is mostly seen in large cerebral infarction, the infarction foci of the compression of the surrounding tissues, caused by ischemia, necrosis of the surrounding tissues, when the blood flow is restored, ischemia, necrosis of the surrounding tissues are prone to blood seepage, called post-infarction hemorrhagic transformation, from the CT view of the cerebral hemorrhage of the dense foci of the flake, the mass of the higher density, the cerebral blood seepage from the CT of the manifestation of the point, or a small diffuse flake of the hemorrhage, its CT value is higher than that of cerebral bleeding. In the case of cerebral hemorrhage, the CT value is slightly lower than that of cerebral hemorrhage, and the clinical symptoms caused by cerebral hemorrhage are less severe than those caused by cerebral hemorrhage.
