Hypopharyngeal cancer with bilateral metastatic lymph nodes - was performed to detect the site of an unknown primary tumour. On axial plane PET/CT images: A, B, C, the examination revealed cancer on the dorsal pharyngeal wall (arrow), and suspected the presence of metastatic lymph nodes in the deep cervical lymphatic regions bilaterally (arrows). Multiplanar Contrast-enhanced-CT images: D, E, F scans in axial, sagittal and coronal planes also demonstrate a mass in the dorsal wall of the hypopharynx, that affects the integrity of the fat layer in the prevertebral space, clearly detectable on sagittal plane image (arrow). Coronal CT scan shows metastatic lymph nodes bilateraly (arrows) with colliquation, however they are less detectable as by PET/CT. Estimated stage by CT: T4b N2c.
