A cystic mass mixture with hemorrhage was shown in four images in the right L2-L3 facet joint with arthritis compressing the L3 right root and the dural sac. A sagittal (a, red arrow) and an axial (b, red arrow) T1-weighted image showed a hyper-signal mixture with equisignal cystic mass. A sagittal (c, green arrow) and an axial (d, green arrow) T2-weighted image showed a hypo-signal mixture with equisignal cystic mass
