A surgical electrode with 16 contacts was implanted in the patient (Figures 1A,B). Hz. However, the electrode shifted to the left after the surgery (Figure 1C), and the size of paravertebral muscles on this side significantly increased (Figure 2).
The images of paravertebral muscles on PET-CT at 3 and 6 months after surgery. (A) The image of paravertebral muscles on PET-CT at 3 months (white arrows indicates hypertrophic paravertebral muscles); (B) The image of paravertebral muscles on PET-CT at 6 months.

Hz. However, the electrode shifted to the left after the surgery (Figure 1C), and the size of paravertebral muscles on this side significantly increased (Figure 2). The fused PET-CT images showed that the CSAs of the bilateral paravertebral muscles in this patient at 6 months after surgery was significantly greater than that in corresponding slices at 3 months (Table 1), especially on the left side (Figure 2).
Biopsy of paravertebral muscles. (A) Hematoxylin-Eosin (HE) staining of the left paravertebral muscle, 20x ; (B) HE staining of the right paravertebral muscle, 20x; (C) Nicotinamide adenine dinucleotide tetrazolium oxidoreductase (NADH-TR) staining, 10x; (D) Periodic acid-schiff (PAS) staining, 20x.

PAS staining showed increased glycogen in the muscle fibers of the bilateral paravertebral muscles (Figure 3).
