Basal ganglia area hemorrhage is a type of brain hemorrhage and is classified mainly according to the location. The basal ganglia, anatomically, includes the thalamus, striatum, nucleus accumbens, and caudate nucleus, and hemorrhage in these areas is called basal ganglia area hemorrhage. Basal ganglia hemorrhage is the most common type of hypertensive cerebral hemorrhage, accounting for about 40%-60% of hypertensive cerebral hemorrhage. It is due to the fact that the middle cerebral artery divides into the doublestriate artery and the middle cerebral artery travels at right angles to each other, so blood flowing to this area is prone to cause ramifications and bleeding from the doublestriate artery, and bleeding from this area is called basal ganglia hemorrhage. The most important feature of basal ganglia hemorrhage is the triple hemianopia sign, i.e., hemianesthesia, hemianomotor deficits, and some patients may also develop isotropic hemianopia. If the basal ganglia hemorrhage is present in the dominant hemisphere, the patient will also develop motor aphasia, which is known as basal ganglia hemorrhage.
