目的 分析咽部淋巴瘤在MRI扫 描上的影像特征，并结合病理症状进行 详细研究。方法 采用回顾性方法分析我 院鼻咽部淋巴瘤患者41例，且所有患者均 MRI平扫和动态增强扫描，并且手术后病 理结果和活检被确诊为鼻咽部淋巴瘤， 进而分析详细的图像特征。结果 弥漫组 一共有24例(24/41，58.53.%)呈现为鼻 咽部黏膜表现为弥漫，厚度增强且为大 致对称；肿块组共有17例局部存在包块 (17/24,41.45%）; 41例患者病灶边界分 明清晰，锋利状，和周围的结构组织分 区清晰，咽喉部肌肉和附近颅骨不存在 异常信号，咽喉部周围筋膜不存在厚度 增加，上颌骨与翼突之间的骨隙不存在 侵犯；颈部肿胀淋巴结MRI增强动态扫描 中信号表现为规律均匀强化，不存在坏 死部位。大直径淋巴结主要位于II区占 83.33%(20/24)。结论 MRI扫描能够清晰 的呈现出病灶的部位、形状和范围，有利 于对患者的确诊率的提高，降低了误诊 率，进而能为患者制定更贴合病情的治疗 方案。

Objective To investigate the imaging features of nasopharyngeal lymphoma on MRI. Methods 41 cases with nasopharyngeal lymphoma in our hospital were retrospectively analyzed. All patients were given MRI scan and enhanced scan. Those diagnosed by histological results and biopsy as nasopharyngeal lymphoma were analyzed the imaging features. Results There were 24 cases in diffuse group (24/41, 58.53.%), showed diffusive nasopharyngeal mucosa, thickness strengthened. 17 cases in mass group existed masses (17/24,41.45%). 41 cases had clear lesions border, sharp shape, partitions were clear with surrounding structural organization, throat muscles and nearby skull existed no abnormal signal, surrounding fascia existed no strengthened thickness, upper jaw bone and pterygoid process existed no invasion. MRI enhanced scan of neck swollen lymph nodes showed regular uniform reinforcement, existed no necrotic areas. Large diameter lymph node mainly in II district account for 83.33%(20/24). Conclusion MRI scan can clearly show location, shape and scope of focus. It is benefit for improvement of diagnose rate, lower misdiagnosis rate and can be seen as more suitable therapeutic schedule.
