Perineural spread (PNS) demonstrated on fluorodeoxyglucose-positron emission tomography computer tomography (FDG-PET/CT), concordant with magnetic resonance imaging (MRI): Large right facial cutaneous squamous cell carcinoma (CSCC) with extensive perineural spread. A Axial post-contrast T1 fat saturation (FS) MRI demonstrates thickening of the right infraorbital nerve, with thickness 6-7 mm, in the right pterygopalatine fossa, right inferior orbital fissure and right infraorbital canal. This is concordant with (B) curvilinear FDG avidity on FDG-PET/CT in the right pterygopalatine fossa, right inferior orbital fissure and right infraorbital canal
