(a) Sagittal T2-weighted magnetic resonance imaging (MRI) of the cervical spine showing a hyperintensity and buckling of ligamentum flavum (circle) at T2-T3 and canal stenosis (arrows) at multiple levels. (b) Sagittal T1-weighted MRI showing hypointensity and buckling of the ligamentum flavum (circle) at T2-T3 and canal stenosis (arrows) at multiple levels. (c) Sagittal short T1-weighted inversion recovery (STIR) MRI showing hyperintensity and buckling of the ligamentum flavum (circle) at T2-T3 consistent with cord edema and canal stenosis (arrow) at multiple levels.

Magnetic resonance imaging showed central canal stenosis that was more prominent on the left, cord signal change at the T2/T3 level [Figures 1 and 2], and diffuse cord edema from the T6-T8 levels [Figures 3 and 4].
(a) Axial T1-weighted FLAIR MRI at T2/T3 level showing thickening/hypertrophy of ligamentum flavum (solid arrows) and decreased spinal canal diameter. (b) Axial T2-weighted MRI at the T2/T3 level showing thickening/hypertrophy of ligamentum flavum (solid arrows) and cord signal change (dashed arrows) moreprominent on the left than the right.
