Acute intracerebral hematoma

Acute intracranial hematoma refers to a hematoma in the brain parenchyma that can occur anywhere in the brain tissue. It occurs in the frontal and temporal lobe, accounting for 80% of the total, followed by the parietal and occipital lobe, which account for about 10%. The rest are located in the deep brain, basal ganglia, brain stem and cerebellum. Superficial intracranial hematomas located in the frontal, anterior, and bottom parts are often associated with cerebral contusions and subdural hematomas, and their clinical manifestations are rapid. Deep hematomas, more than in the white matter of the brain, are caused by tearing and bleeding of deep blood vessels caused by brain deformation or shear. When the hemorrhage is small and the hematoma is small, the clinical manifestations are slow. When the hematoma is large, the hematoma located near the basal ganglia, thalamus, or ventricle wall can rupture into the ventricle and cause intraventricular hemorrhage.
