The vascular territory of the vertebral body. (a) Pores of vertebral arteries in nutrient arteries anterior to the vertebral body, periosteal arteries, and rete-like arteries in metaphysis (white arrow). (b) Enhanced CT showed the nutrient artery derived from the right segmental artery extended towards the vertebral body (red arrow) and areas of blood supply to the tumor in vertebral body (red outline). (c) Enhanced CT showed the nutrient artery originated from the right segmental artery was directed to the vertebral body (red arrow) and areas of blood supply to the tumor in vertebral body (red outline). (d) Enhanced CT showed the nutrient artery was sent from the left segmental artery to the vertebral body (red arrow) and areas of blood supply to the tumor in vertebral body (red outline). (e) Enhanced CT showed bilateral segmental arteries, posterior branches, spinal branches and anterior branches of vertebral canal formed the nutrient arteries that anteriorly supplied the blood flow of posterior vertebral body (red arrow). (f) Enhanced CT showed areas of blood supply to the tumor in the posterior vertebral body (red outline)
