Figure 2: Sagittal MR [bold orange arrow (a)] showed hypointense signal in the lesion extending from the MCF along the V nerve, with sagittal FDG-PET (b) and fused PET/MRI (c) showing increased curvilinear FDG uptake in the lesion. Coronal MR (d), coronal FDG-PET (e), and fused PET/MR image (f) showed the contiguous perineural spread (PNS) of the lesion from the right parotid up to the right paracavernous region
