［摘要］ 目的 回顾warthin瘤和腮腺多形性腺瘤的临床特点，分析MSCT影像在Warthin瘤和腮腺多形性腺瘤鉴别诊断中的作用。方法 选取Warthin瘤65例和腮腺多形性腺瘤62例作为研究对象，分析其临床病例特点及MSCT影像学特征，所得数据均采用SPSS23.0 软件包进行统计学分析。 结果1. 临床特点方面Warthin 瘤平均年龄和吸烟率均高于腮腺多形性腺瘤组且有统计学差异（Ｐ＜0.05）。2.MSCT影像学方面腮腺 Warthin 瘤与腮腺多形性腺瘤在病灶均质性和形态方面差异无统计学意义( P＞0.05)。 但在MSCT边界清晰率和平均密度值方面二者之间有明显差异，结果有统计学意义( P＜0.05)。结论 在MSCT影像中，Warthin 瘤的边界清晰度和平均密度值都高于腮腺多形性腺瘤。 双期增强扫描中多形性腺瘤与warthin瘤呈现不同的强化方式，这对临床医生明确肿物的大小范围和术前鉴别有重要的诊断参考价值。

Objective To compare and analyze the clinical value of MSCT dual phase enhanced scanningl to diagnosis of Warthin's tumor and parotid pleomorphic adenoma（PA） in the clinical significance. Methods A total of 65 Warthin's tumor patients and 62 PA patients who enhanced MSCT before surgery were enrolled.The clinical value of the two enhance scanning methods in differential diagnosis Warthin's tumor and PA was analyzed by SPSS 23.0 software package. Results 1.In terms of clinical characteristics, the average age and smoking rate of Warthin’s tumor group were higher than PA , and the differences were statistically significant (P < 0.05). 2. In MSCT plain scanning there was no significant difference in lesion homogeneity and morphology between Warthin’s tumor and PA (P > 0.05). However, there were significant differences between them in CT boundary clarity rate and the mean density , and the results were statistically significant (P < 0.05). Conclusion It is important clinical value for MSCT plain scanning of the parotid gland in differential diagnosis with Warthin’s tumor and PA .
