摘　　要：目的探讨鼻咽喉头颈部淋巴瘤的CT及MRI表现,并与病理对照分析。方法收集68例经病理证实的鼻咽喉头颈部淋巴瘤的临床、病理及CT和(或)MRI资料,分析其影像学特点。结果 68例鼻咽喉头颈部淋巴瘤病例中,鼻腔鼻窦14例(20.6%),韦氏淋巴环13例(19.1%),咽旁间隙8例(11.8%),颈部淋巴结群33例(48.5%)。组织学分类中,非霍奇金淋巴瘤62例(91.2%),B细胞型41例(60.3%),其中以弥漫大B细胞型27例(39.7%)最为常见,其次为滤泡性淋巴瘤6例(8.8%);T细胞型21例(30.9%),其中结外NK/T细胞淋巴瘤16例(23.5%)。根据病变形态可分为5型。弥漫肿胀型15例(22.1%),单一肿块型3例(4.4%),多发淋巴结肿大27例(39.7%),溃疡型7例(10.3%),混合型16例(23.5%)。结论 CT和MRI能清楚显示鼻咽喉头颈部淋巴瘤的部位、形态、范围,并对组织学类型有一定提示作用,对临床诊断和治疗有重要价值。Objective To investigate CT and MRI findings of the lymphoma of head and neck comparing with the operative and pathological findings.Methods 68 cases of lymphoma proved by pathology were retrospectively analyzed.The image features of this lymphoma were summarized.Results 14 cases were located in nasal cavity and nasal sinuses,13 in Waldeyer ring,8 in parapharyngeal space,33 in cervical lymphonode group.62 cases were non-Hodgkin lymphoma,among which B-cell lymphoma accounted for 60.3%（41 cases）.The most common histologic subtype was diffuse large B cell lymphoma（27 cases,39.7%）,followed by follicle lymphoma（6 cases,8.8%）.27 cases were T-cell lymphoma,among which NK/T cell lymphoma accounted for 23.5%（16 cases）.15 cases were diffuse swelling type,3 single mass type,27 multinodular of mass type,7 ulcer or necrotic type and mixed type（16 cases,23.5%）.Conclusion CT and MRI can provide the information on the position,shape and range of lymphoma of head and neck.They are of high clinical value in diagnosis and treatment of lymphoma of head and neck.
