[Abstract] Objective: To study the appearances on MRI imaging of the nasopharyngeal lymphoma (NPL).Materials and Methods: The MRI images of 23 patients with pathologically confirmed NPL were retrospectively analyzed. According to the morphology, the NPL were divided into diffuse infiltrative and focal bump groups. All NPL were assessed for necrosis, local invasion and lymphadenopathy.Results: Fourteen cases were divided into diffuse infiltration group, and 9 cases were divided into focal bump group. Only one patient was observed small patchy necrosis, and the rest were homogeneous on MRI. There was no case present local invasion. Swollen palatine and/or lingual radix tonsil were found in 9. Swollen tonsils were bilateral and symmetrical in 7 cases which come from diffuse infiltration group. Lymphadenopathy was present in 13. Eleven cases, which were bilateral and symmetrical, all come from diffuse infiltrative group. There was no necrosis occurred in all lymphadenopathy. The largest lymph node was located at zone II in 12 cases and zone I in 1 case.Conclusions: There were typical features of NPL on MRI. The lesions at nasopharynx (NP) and lymphadenopathy were homogeneous, infrequent necrosis. Deep structures or the skull base were not involved into. And the diffuse infiltrative group could invade multiple walls of NP, and most of all are bilateral symmetry lymphadenopathy. Bilateral symmetry palate and/or tongue tonsil swollen were complicated by more than half of NPL too.
