case_images: a Sagittal T2-weighted cervical MRI in neutral position shows marked spinal cord atrophy at the C4-C6 vertebral level. b Axial T2-weighted cervical MRI in neutral position shows hyperintensity of the right-sided intramedullary and a flattened spinal cord at the C4/C5 vertebral level. c Sagittal T2-weighted cervical MRI in flexion position shows expansion of the posterior extradural space and forward displacement of the spinal cord at the C3-C6 vertebral level. d Gadolinium-enhanced T1-weighted MRI with flexion position showed homogeneous enhancement of the posterior extradural space at the C3-C6 vertebral levels.

case_images: T1 and T2-weighted cervical MRI in the neutral position, marked atrophy of the spinal cord was evident and the curve of the cervical was kyphotic at the C4-C6 vertebral level (Fig. 1a). The apex of the cervical kyphosis was located at the C4/C5 vertebral level. Axial T2-weighted MRI showed a flattened spinal cord and intramedullary signal hyperintensity on the right side (Fig. 1b). Sagittal T2-weighted cervical MRI in the flexion position showed expansion of the posterior extradural space and forward displacement of the spinal cord at the C3-C6 vertebral level (Fig. 1c). C3-C6 vertebral levels (Fig. 1d). Cervical myelography in a flexed position showed cervical cord atrophy at the C4-C5 vertebral levels with a narrowed dural canal and forward displacement of the cervical cord at the C4-C6 vertebral levels (Fig. 2).
