| Site | CT/MRI findings |
| Nasopharynx | Polypoid mass | Diffuse thickening of the mucosal wall of nasopharynx | Less extension outside the nasopharynx | Less invasion into surrounding structures such as prevertebral muscle, nasal cavity, and oropharynx | Lesion necrosis especially within small nasopharyngeal lesion | Destruction of striped feature |
| Lymph node | Homogeneous contrast enhancement (early phase) | Peripheral rim enhancement with central necrosis (progression phase) | Fibrosis and calcification may have homogeneous appearance without enhancement (late phase) | Shortest axial diameter ≥ 5 mm for retropharyngeal LN and ≥10 mm for LN of neck |
