Figure 5
CT findings of removed vertebral column unit. (a) 3D CT: coronal view. (b) Coronal section: bilateral L3/L4 zygapophyseal joints were not fused. (c) Right sagittal section: L4/L5 zygapophyseal joint was not seen, but L3/L4 zygapophyseal joint was clear. (d) 3D CT: sagittal view. (e) Left sagittal section: L4/L5 zygapophyseal joint was obscure, but L3/L4 zygapophyseal joint was clear. (f) Axial section: though bilateral, L4/L5 bilateral zygapophyseal joints were obscure and bilateral L3/L4 zygapophyseal joints were clear.
