Hypertensive cerebral hemorrhage can occur anywhere in the skull, but it most often occurs in the internal or external capsule, which is often referred to by clinicians as basal ganglia hemorrhage. The internal capsule is where the nerve fibers in our brain are more concentrated as they travel downward. Therefore, when the internal capsule is damaged or compressed by the hemorrhage, it often shows what we often call the triple deviation sign, because of the cross innervation of brain nerves, and the hemiparesis on the contralateral side of the brain hemorrhage focus, the contralateral hemianopia, and the contralateral hemianesthesia, which is the triple deviation sign. Because the external capsule is adjacent to the internal capsule, the hemorrhage of the external capsule is easily combined with the injury and edema of the internal capsule area, and the triple deviation sign appears.
