Extensive perineural spread (PNS) not detected by fluorodeoxyglucose-positron emission tomography computer tomography (FDG-PET/CT). A Magnetic resonance imaging (MRI) T2 axial demonstrates extensive right trigeminal nerve PNS in Meckel’s cave. B MRI T1 axial post-contrast fat saturation (FS) demonstrates extensive right trigeminal nerve PNS in Meckel’s cave as a mass with minimal enhancement. C Computer tomography (CT) post-contrast demonstrates mass like extensive right trigeminal nerve PNS in the Meckel's cave. D FDG-PET/CT, extensive right trigeminal nerve PNS not detected on FDG-PET/CT either obscured by FDG avidity in the adjacent brain or minimal FDG avidity in the PNS
