Figure 6: Perineural spread along V3 nerve: 57-year-old male, with Ca left lower alveolus, presented with trismus. Transaxial fluoro-deoxy-glucose positron emission tomography/computed tomography (a) uptake in soft tissue mass in the left lower alveolus widening and eroding the inferior alveolar canal (long black arrow). Coronal computed tomography (b) enhancing soft tissue mass extending from the infratemporal fossa intracranially through the widened foramen ovale (short black arrow) and showing no significant fluoro-deoxy-glucose uptake in the coronal fused fluoro-deoxy-glucose positron emission tomography computed tomography (black arrowhead) (c). Serial sections of axial postcontrast magnetic resonance sequences (d-f) reveals mass in the left masticator space extending cranially along the mandibular nerve (white arrowhead), trigeminal ganglion (short white arrow) up to the lateral aspect of pons (long white arrow)
