Objective To characterize the features of Nasopharyngeal non-Hodgkin's lymphoma (NHL) on MR imaging and find the main points to differentiate it from the other nasopharyngeal tumors.Methods The MR images of 41 patients with pathologically and immunohistochemically proven nasopharyngeal NHLs were reviewed retrospectively. Images were assessed by the size, invasive extent,signal intensity of primary nasopharyngeal tumor, and the distribution of cervical lymphadenopethy. The difference of regional tissues invasion and cervical lymphadenopathy distribution between the patients with B-cell NHLs and the patients with T-cell or NK/T-cell NHLs were analyzed by Pearson's Chi-Square test or Fisher's exact test Results Of the 41 patients, 26 patients had mature B-cell lymphoma, two patients with mature T-cell Iymphoma, and thirteen patients showed Nature killer/T-cell lymphoma in nasopharynx. MRI revealed that NHLs of nasopharynx can be showed as thickening of nasopharyngeal mucosa and (or) lumps in nasopharynx, which were slightly hyper-intensity on T2-weighted images, and intermediate signal intensity (similar to muscle) on T1 -weighted images, with mild or moderated enhancement following contrast medium administration. Twenty four cases had symmetrical disease of all walls of nasopharynx, and 17 cases had unsymmetrical tumor. Of all cases, 5 cases had superficial ulcerations, 9 cases had exceed nasoharynx invasion spreads superficially along the mucosa, 23 cases had invasion of lingual and (or) palatine tonsils,20 cases showed invasion of parapharygeal muscles, 12 cases suffered from skull base bone infiltration,25 cases had retropaharyngeal lymphadenopathy, and 27 cases had cervical lymhadenopathy. Patient with nasopharyngeal Nature killer/T-cell lymphoma had a higher incidence of exceed nasopharynx invasion,parapharyngeal structures invasion, and superficial ulcerations (the cases were 8, 11, 4 in patient with T-cell or N K/T-cell lymphoma, and 4, 10, 1 in patients with B-cell lymphoma, respectively). Patients with nasopharyngeal B-cell lymphoma had a higher incidence of inasion of lingual and (or) palatine tonsils.Conclusions Nasopharyngeal NHL is a homogeneous tumor that tends to diffusely involve all walls of the nasopharynx and spread in an exophytic fashion to fill the airway, rather than infiltrating into the deep tissues. Different pathological types of nasopharyngeal NHLs have some different appearance on MRI between each other. A large tumor in nasopharynx that fills the nasopharynx cavity, with no or minimal invasion into deep structures, but with invasion extend down into the lingual and(or)palatine tonsils, may suggest the diagnosis of nasopharyneal NHL.
