Figure 3: Indirect evidence of PNS on PET/CT seen as asymmetric decreased FDG uptake in the atrophied right lateral rectus muscle (a) and right orbicularis oculi/orbicularis oris muscle (b and c) which is supplied by VII nerve. Asymmetric decreased FDG uptake was also noted in the right mylohyoid muscle (c), secondary to PNS along inferior division of mandibular nerve with erosion of the right mandibular foramen [dashed white arrow, (d)]
