Figure 2: (a) T2W image shows hyperintense signals in the cord with atrophy from C5 to C7 (arrow). (b) T2W image showing the “snake eye appearance” (arrows). (c) MRI in flexion shows dural detachment from C4 to D2 vertebral levels with flow voids (arrow). (d) C2–C7 vertebrae dorsal line shows reversal of lordosis. (e and f) Post-contrast T1W flexion study (FS) showing the sagittal and axial images in flexion, respectively, with posterior epidural enhancement prominent on the left side (thick arrow) extending from the C4 to D2 level (thin arrow). (g and h) X-ray of the cervicodorsal spine in flexion (40.8°) and extension (angle: 50.73°) with an increased range of motion
