摘　　要：目的 探讨喉部非霍奇金淋巴瘤（NHL）的CT和MRI诊断价值。方法 回顾性分析26例喉部NHL患者的临床资料、CT和MRI表现及病理。结果 26例喉部NHL包括14例弥漫大B细胞淋巴瘤，6例NK/T细胞淋巴瘤，2例滤泡性淋巴瘤，2例小淋巴细胞淋巴瘤，血管免疫母细胞淋巴瘤和外周T细胞淋巴瘤各1例。喉部NHL的CT和MRI表现：（1）均匀的等密度软组织，T2WI稍高信号，T1WI等信号，中等均匀强化；（2）双侧对称的弥漫性病变；（3）主要沿黏膜下、脂肪间隙蔓延，肌肉及软骨的侵犯和坏死偶尔可见；（4）可伴随韦氏淋巴环病变。对具有上述影像表现的年轻男性，在排除结核或感染后，应考虑到淋巴瘤的可能。结论 CT和MRI能清晰显示喉部NHL特征，对喉部NHL的诊断有重要价值。Objective To discuss the value of CT and MRI in diagnosis of laryngeal non-Hodgkin＇s lymphoma（NHL）.Methods The clinical data, CT and MRI findings and pathology of 26 patients with laryngeal NHL were analyzed retrospectively.Results Of 26 patients with laryngeal NHL, 14 were diffuse large B-cell lymphoma,6 were NK/T-cell lymphoma,2 were follicular lymphoma,2 were small lymphocytic lymphoma（SLL）, 1 was angioimmunoblastic lymphoma and 1 was peripheral T-cell lymphoma.CT and MRI findings of laryngeal NHL： （1） laryngeal NHL showed homogeneous density on CT, slightly high signal intensity on T2 WI,intermediate signal intensity on T1 WI and moderate homogeneous enhancement;（2） laryngeal NHL was symmetrical and diffuse in appearance;（3） laryngeal N H L tended to spread through the submucosal and fat space, while muscle or cartilage invasion was quite rare but existed; （4） multisite lesions in Waldeyer＇s ring were obseverd occasionally.For those young male presenting diffuse multisite laryngeal lesion without a history of tuberculosis,a diagnosis of NHL should be raised.Conclusion CT and MRI can show the characteristics of the laryngeal NHL exactly,thus have applied value in detecting laryngeal NHL.
