Hypopharyngeal cancer, stage T4aN2c. A: axial T2-weighted, B: axial non-enhanced T1-weighted MR images show cancer of the hypopharynx involving the dorsal and right lateral pharyngeal wall, avoiding the retropharyngeal space. Note the intact prevertebral fat, clearly obtainable on T1-weighted image (arrow). C: axial post-contrast T1-weighted MR image with fat suppression at the level of the tongue base, tumour infiltrates the tongue base crossing the midline to the opposite side. Metastatic lymph nodes are present bilaterally (arrows).
