摘　　要：目的探讨头颈部非霍奇金淋巴瘤的MRI影像特征。方法回顾性分析12例经病理证实的头颈部非霍奇金淋巴瘤患者的MRI影像表现。结果12例患者中，病变表现为肿块型的4例，弥漫型的3例，多发淋巴结肿大型3例，混合型的2例。单发于颈部淋巴结群者3例，单发于扁桃体者1例，颈部合并韦氏淋巴环多部位受累者8例。MRI检查T1WI呈稍低信号，T2WI为均匀稍高信号，增强扫描呈轻一中度均匀强化。病理分类：B细胞来源10例，NK／T细胞来源2例。结论头颈部非霍奇金淋巴瘤具有一定的影像学特征，影像表现与病理分型有一定相关性；MRI能清楚显示其生长部位、形态及侵犯范围，在其诊断和鉴别诊断方面具有重要的应用价值。Objective To evaluate the imaging features of non-Hodgkin＇s lymphoma （NHL） of the head and neck on magnetic resonance scans. Methods The imaging of MR was retrospectively analyzed in 12 pa- tients with histopathologically proved NHL of the head and neck. Results There were four types of lesion ap- pearances. Mass type was in 4 patients, diffusion type was in 3 patients, multinodular enlargment was in 3, and mixed type was in 2. The lesions developed in cervical lymphonode group in three patients, in palatine tonsil in one patient, and in Waldeyer＇s ring in 8 patients. The lesions were slightly hypointensed on T1WI and slightly hyperintensed on T2WI in MRI. They were moderately enhanced after contrast administration. Pathological classification revealed 10 cases of NHL were originated from B-cell and 2 were from NK/T-cell. ConclusionsNHI, of the head and neck has some characlerislic, imaging features.
