Based on the neuro-imaging findings Chung et al. classified [[thalamic hemorrhage]] into four regional types and one global type according to the primary bleeding sites: (i) anterior type occurring in the territory of the [[tuberothalamic artery]], (ii) posteromedial type occurring in the territory of the thalamic-subthalamic paramedian arteries, (iii) posterolateral type occurring in the territory of the thalamogeniculate arteries. (iv) dorsal type occurring in the territory of the posterior choroidal arteries and (v) global type occupying the entire area of the thalamus
