Figure 1-a: transaxial c.e.CT scan shows primary epiglottic lesion (white arrow); Fig. 1-b: transaxial c.e.CT scan shows both the increased left lateral cervical lymph nodes (white arrow), both some small right lateral cervical lymph nodes with contrast enhancement (red arrow).  FDG uptake of the primary lesion in the right epiglottis (SUVmax = 10, SUVmean = 6.3, MTV = 1.9 cm3, TLG = 12) and also in correspondence of the II and III level in the contralateral side (SUVmax = 15, SUVmean = 8.5, MTV = 14.9 cm3, TLG = 126.6). Figure 1-c: transaxial PET/CT scan shows an increased [18F]-FDG uptake area on the right versant of the epiglottis (white arrow); Fig. 1-d: transaxial PET/CT scan demonstrates clearly that right lateral cervical lymph nodes are not pathological (red arrow) and confirm, on the left side, the adenopathy (white arrow).
