18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography axial imaging. Preoperative image shows abnormally higher FDG uptake in the right obliquus capitis inferior (arrow) (a). Postoperative image shows the disappearance of FDG uptake in the right obliquus capitis inferior (arrow) (b).

The 18F-FDG-PET/CT imaging showed FDG uptake in the right obliquus capitis inferior muscle [Figure 1]. Three months after discharge, the 18F-FDG-PET/CT showed complete disappearance of the increased FDG uptake in the right obliquus capitis inferior muscle [Figure 1].
Perioperative image of selective peripheral denervation. The arrow shows the C1 anterior rootlet. Afterward, this nerve was cut.
