8y FS Border Collie with possible infected tooth. There is marked osteolysis and irregular bone production surrounding the caudal left
mandible (a,b: open arrows). Multiple teeth are absent. There is a large soft‐tissue mass associated with the osseous lesion, which is
intensely, heterogeneously contrast enhancing (d: arrows). The 3D image shows the extent of the osseous component of mandibular
lesion (e). Biopsy confirmed squamous cell carcinoma.

9y FS Domestic Shorthair with a neck mass. On contrast‐enhanced images of the head, there is a large, intensely enhancing mass in the
left soft palate and tonsillar region (a,b: arrows). The contralateral mandibular lymph node is markedly enlarged and heterogeneously
contrast enhancing (b,c: open arrows). Fluid is visible in the tympanic bulla secondary to the soft palate thickening (c). Postmortem
examination confirmed primary squamous cell carcinoma with regional lymph node metastasis.
