摘要
目的探讨咽淋巴环非霍奇金淋巴瘤不同病理类型的影像学征象,以提高影像学认识。方法回顾18例经病理证实咽淋巴环非霍奇金淋巴瘤的CT、MRI表现,结合病理类型进行对比分析。结果在18例非霍奇金淋巴瘤中,病灶局限性11例(11/18),弥漫性7例(7/18),伴颈部淋巴结肿大10例。病理类型:B细胞型13例(72%),NK和T细胞型5例(28%)。B细胞型以局限性多见(10/13),扁桃体好发(8/13),密度和信号均匀(12/13),边界清晰(10/13),常伴颈部淋巴结肿大(8/13)。NK/T细胞型以弥漫性多见(4/5),易累及鼻咽部(4/5),边界不清(4/5)、密度和信号不均匀多见(3/5),其内可见气泡影(2/5),易侵犯鼻腔并铸形(3/5)和骨质侵蚀破坏(2/5)。结论咽淋巴环不同病理类型的非霍金奇淋巴瘤影像学具有一定特点,有助于鉴别诊断。
Objective To improve the imaging cognition by exploring the imaging findings of the different pathological type non hodgkin lymphoma in waldeyer ring. Methods The CT and MRI findings of 18 cases of non hodgkin lymphoma in waldeyer ring were reviewed, which were analysed comparatively according to the pathological type. Results In 18 ca ses of non-hodgkins lymphoma, local lesion was found in 11 patients （11/18）, diffuse lesion in 7 cases （7/18）, cervical lymph node enlargement in 10 cases. B cell type was found in 13 cases （72%） and NK and T cell type in 5 patients （28%） were diagnosed by pathology. In the B cell type, the lesions that occurred in tonsil （8/13） showed frequently local growth （10/13）, homogeneous density and signal （12/13）, clear boundary （10/13）, and cervical lymph node enlargement （8/ 13）. In the NK and T cell type, the lesions that involved in the pars nasalis pharyngis（4/5） manifested diffuse growth （4/ 5） , unclear boundary and uneven density and signal （3/5） , in which air-bubble in the interior was observed and was prone （2/5）, and was prone to infringing upon the nasal and casting along the nasal （3/5）, to destroying bone （2/5）. Conclusion The imaging findings of different pathological type non-hodgkin lymphoma in waldeyer ring have some characteristics, which help in the differential diagnosis.
