摘　　要：目的:探讨涎腺淋巴上皮瘤及淋巴上皮癌的临床、病理表现及增强MRI影像的特点。方法:对11例经手术及病理分别确诊为涎腺淋巴上皮瘤和淋巴上皮癌的病例进行回顾性分析。结果:共1 1例,其中男性5例,女性6例;病变位于腮腺9例,颌下腺2例;良性9例,恶性2例。MRI检查结果11个病灶中10个(81.8%)在T1WI为略低信号,10个(90.9%)在T2WI表现为略高信号,10个(90.9%)确诊增强扫描后显示强化。结论:涎腺淋巴上皮瘤及淋巴上皮癌无明显临床和MRI特征性表现,术中病理是确定手术治疗方案所必需的。Objective：To discuss the clinical,pathological and MRI characteristics of lymphoepithelial lesions. Methods：Eleven cases（5 males and 6 females） were retrospectively reviewed,in which nine niduses were found in the parotid gland and two niduses in submandibular gland.Results：Nine cases were found benign lymphoepithelioma and two cases were lymphoepithelial carcinoma.Nine focuses demonstrated low signal intensity at TIWI level by MRI.Ten focuses showed hypointensity at T2WI level.Ten focuses displayed inhomogeneous enhanced.Conclusion：Pathology examination is recommended as an effective method for treatment planning of lymphepithelioma and lymphoepithelial carcinoma.
