Nasopharyngeal carcinoma

Case contributed by A.Prof Frank Gaillard
MRI

MRI through the nasopharynx and base of skull of an Asian patient including contrast enhanced fat suppressed sequences demonstrates a large nasopharyngeal mass invading the cavernous sinuses (especially on the left), clivus and pterygopalatine fossa. Large right sided lymph nodes are present.

Case Discussion

Features are consistent with a nasopharyngeal carcinoma, which was confirmed on biopsy (non-keratinizing squamous cell carcinoma, EBV positive).

Final Diagnosis:

Both biopsies show similar features, with invasive poorly differentiated non-keratinizing squamous cell carcinoma involving fragments of soft tissue and bone. The tumor is positive for EBV by in situ hybridization for EBER. EBV is highly associated with nasopharyngeal carcinoma.
