Figure 1: Atrophy of bilateral intrinsic hand muscles. It was more prominent on the ulnar side and more severe on the right side.
Figure 2: A, B: Neutral position the sagittal T2-weighted MR image shows spinal cord atrophy at the C4/5 to C6/7 vertebral body, without enlargement of the posterior epidural space.
C: The flexion MR image sagittal T2-weighted image, the study shows anterior widening of the posterior epidural space about C3-C6/7 level (red arrows) with a few flow void signals inside.
Figure 3: A, B: Neutral position the sagittal T2-weighted MR image shows an unchanged spinal cord atrophy at the C4/5 to C6/7 vertebral body, without enlargement of the posterior epidural space.
C- E: Unchanged anterior widening of the posterior epidural space about C3-C6/7 level (red arrows) with a few flow void signals inside on flexion MR image sagittal T2-weighted image and contrast enhancement after supportive treatment after about 3 months.
