A 63-year-old man with right level IIa node metastasis arising from cancer of the gum (pT3N2c). a CT of PET/CT shows one swollen lymph node 10 mm in longest diameter at right level IIa (short arrow) and one swollen lymph node 11 mm in longest diameter at left level IIa (long arrow), suggesting absence of nodal cancer spread. b FDG-PET/CT shows moderate FDG uptake (SUVmax:5.34) corresponding to the right level IIa node seen in a (short arrow), suggesting the presence of nodal cancer spread. And mild FDG uptake (SUVmax:2.31) corresponding to the left level IIa node seen in b (long arrow), suggesting absence of nodal cancer spread. Histopathological examination of the specimen confirmed extensive lymph node involvement by cancer in only the right node. CT gave a false-negative result for the right node, whereas FDG-PET/CT gave a true-positive result. Both CT and FDG-PET/CT gave true-negative results for the left node
