Subarachnoid hemorrhage is also a kind of cerebral hemorrhage. Cerebral hemorrhage generally refers to hemorrhage in brain parenchyma. It is an artery in brain parenchyma that ruptures due to prolonged hypertension or other reasons. Blood flows into brain parenchyma, resulting in space-occupying effect. Hemorrhagic foci can be seen in brain parenchyma on CT. In this case, it is considered to be cerebral parenchyma hemorrhage. It mainly affects some neural functions, such as motor function, language function and reaction performance. Subarachnoid hemorrhage, it is generally in the arachnoid blood vessels show aneurysms, or arterial malformations show rupture, bleeding, it mainly hemorrhage accumulation in the sulcus, cerebral fissure and other places performance, and brain parenchyma hemorrhage is different.
