Nasopharyngeal mass inseparable from lymphatic tissue, measuring 4.0 x 3.6 x 3.0 (TRV x AP x CC) cm, slightly hypointense on T2WI, showing diffusion restriction, and enhancing quite homogeneously. The mass bulges into the right choana. Markedly enlarged retropharyngeal lymph nodes (up to 3 cm on left). Enlarged jugular (stations II and III) lymph nodes, bilateral. Fluid in right mastoid air cells, most probably representing blocked drainage. Asymmetrical enhancement of the pterygoid venous plexus, appearing more engorged on the right. Enhancement involving tail of right parotid gland, the significance of which is not entirely clear; possibly enhancement of the plexus itself.
In summary:
- nasopharyngeal mass, possibly of lymphatic origin
- substantially enlarged cervical lymph nodes, as depicted above - lymphoma?
