(A) Cervical plexus MRI: fluid attenuation inversion recovery (FLAIR) shows slightly thickened bilateral nerve roots at C4/C5-C6/C7. (B) Lumbosacral plexus MRI: fluid attenuation inversion recovery (FLAIR) shows bilateral nerve root thickening at the L1/L2-L4/L5 intervertebral space, with slightly higher signal intensity, especially at L2/L3-L4/L5.

An MRI of the cervical plexus is shown in Figure 1A, an MRI of the lumbosacral plexus in Figure 1B, and musculoskeletal ultrasounds are shown in Figure 2.
Ultrasounds 4 months after the onset of the disease, the right C6 nerve root was thickened, with a thickness of 0.476 cm (A). 6 months after the onset of the disease, the right C6 nerve root was thickened, with a thickness of 0.467 cm (B). 11 months after the onset of the disease, the right C6 nerve root was thickened, with a thickness of 0.426 cm (C).
