Intrinsic muscle wasting in right hand.
Figure 2
Cervical spinal MRI on neutral and flexion position.
(A) Normal unenhanced sagittal T2-weighted imaging on neutral position.
(B) Unenhanced sagittal T2-weighted imaging shows flow voids (yellow arrows) in the widened posterior epidural space on flexion position.
(C) The flow voids signals were hyperintense on T2 fat-saturated imaging.
(D) Normal unenhanced axial T2-weighted imaging on neutral position.
(E–F) Axial T2-weighted imaging shows flow voids (red arrows) in the widened posterior epidural space on flexion position from C6 to T3 levels.
