CASE HISTORY / CLINIC:
Patient with pronounced hinderance of nasal breathing. Condition has been progressive for many months now. Swollen lymph nodes on both sides of the neck a couple of weeks ago.


FINDINGS:
The axial CT image after contrast administration (upper left picture) reveals a nearly total occlusion of the nasopharynx by a poorly enhancing mass. The mass appears a bit hyperdense, occluding the nasopharynx in the coronal image after contrast administration (upper right image). The ethmoid sinus that lies superioir to the mass is clear. The sagital image after contrast administration excellently demonstrates the cranio-caudal spread of the nasopharyngeal tumor as well as the demarcation from the clivus.


DIAGNOSIS:
Nasopharyngeal carcinoma


DIFFERENTIAL DIAGNOSIS:
Lymphoma
