| 目的 总结涎腺混合瘤与Warthin瘤的超声造影特征。方法 回顾性分析经超声造影检查并手术病理证实的17个涎腺混合瘤和16个Warthin瘤的超声造影特征。结果 混合瘤超声造影表现以同进（76.47%）、向心性（64.71%）、不均匀性（76.47%）、低增强（70.59%）为主，增强后边界清晰（88.24%），可见增强环（94.12%），增强后肿块范围不增大（88.24%）。Warthin瘤超声造影表现以快进（50%）、非向心性（87.5%）、不均匀性（62.5%）、高增强（56.25%）多见，增强后边界清晰、可见增强环和增强后肿块范围不增大（均为93.75%）。混合瘤与Warthin瘤的增强方向和增强强度比较差异有统计学意义（P＜0.05）。结论 混合瘤与Warthin瘤的超声造影表现具有一定的特征性，增强方向和增强强度指标有助于二者的鉴别诊断。 |

| Abstract: |
| Objective To summarize the contrast-enhanced ultrasonic characteristics of of pleomorphic adenomas and warthin tumors of salivary gland. Methods 17 pleomorphic adenomas and 16 warthin tumors underwent contrast-enhanced ultrasound examination and confirmed by surgical histopathology， were retrospectively analyzed. Result The contrast-enhanced ultrasonographic of pleomorphic adenomas were mainly synchronal (76.47%), centripetal (64.71%), inhomogeneity (76.47%) and hypo-enhancement (70.59%), with clear boundary after enhancement (88.24%), visible enhancement rim (94.12%), and no increase in the mass scope after enhancement (88.24%). Warthin tumors was characterized by fast fill-in (50%), non-centrality (87.5%), inhomogeneity (62.5%), and hyper-enhancement (56.25%). After enhancement, the boundary was clear, the enhancement rim was visible, and the mass scope was not increased (93.75%). There were statistically significant differences in the enhancement direction and enhancement intensity between pleomorphic adenomas and warthin tumors（P＜0.05）. Conclusion The contrast-enhanced ultrasound of pleomorphic adenomas and warthin tumors have certain characteristics， and the enhancement direction and enhancement intensity parameters are helpful to differentially diagnose pleomorphic adenomas and warthin tumors． |
