Distinct imaging features of different pathological subtypes of B cell non-Hodgkin′s lymphomas of the nose and pharynx ministry type NK/T cell
Objective
To investigate the distinct imaging features of different pathological subtypes of non-Hodgkin′s lymphomas(NHL)of the nose and pharynx and to improve its diagnostic accuracy.
Methods
A retrospective study was performed on the imaging materials(including CT or MRI)of 32 patients who were confirmed as NHL of the nose and pharynx by pathology.The materials were divided into two groups: NK/T cell lymphoma(NKTCL)and B cell lymphoma(BCL). The characteristics of the site, size, morphology, growth pattern, regional structure invasion of these lymphomas were evaluated and compared.The results were analyzed by Chi-quare test.
Results
A total of 12 cases(37.5%)were NK/T cell type, 10 cases(83.3%)mainly had nasal cavity involvement, 2 cases(16.7%)showed Waldeyer′s ring involvement, which were characterized by nasal soft tissue with mold growth.Among these, 7 cases(58.3%)had superficial ulcerations, 6 cases(50.0%)with regional structure invasion, 2 cases(16.7%)lymph node involvements.Besides, 20 cases(62.5%)were B cell type NHL.Among these, 19 cases(95.0%)had Waldeyer′s ring involvement and 1 case(5.0%)occurred in nasal cavity with pharyngeal lymphatic loop soft tissue incrassation, and 2 cases(16.7%)had regional structure involvement of pharyngeal space and bone.All cases showed cervical lymphadenopathy.Results of the Chi-square test showed that NKTCL had a higher incidence of nasal cavity involvement than B cell type NHL(χ2=20.401, P=0.000)and regional structure invasion (χ2=6.400, P=0.011), as well as superficial ulcerations (χ2=11.378, P=0.001). BCL had a higher incidence of Waldeyer′s ring involvement and creeping growth pattern(χ2=20.519, P=0.000), as well as lymphadenopathy(χ2=23.058, P=0.000)compared to NKTCL.
Conclusion
Primary NHLs of the nose and pharynx of different pathological subtypes has some characteristics on imaging, which may have supplementary value in the lymphoma diagnosis.
