摘要
目的:研究腮腺混合瘤和腺淋巴瘤彩色多普勒血流图特点,提高超声诊断符合率。材料和方法:57例经手术病理证实的腮腺混合瘤和腺淋巴瘤声像图资料,综合分析二维图像加上彩色多普勒血流指标。结果:超声诊断混合瘤42例、腺淋巴瘤15例,诊断符合率93%。混合瘤与腺淋巴瘤声像图有特征有类似之处。结论:超声对病变检出率为100%,是发现腮腺肿块的首选方法,虽然混合瘤与腺淋巴瘤声像图特征有时重叠,但应用高频彩色多普勒进行血流分析有望鉴别。
Purpose： Studying the ultrasound imaging of parotid pleomorphic adenoma and adenolymphoma, to promote the diagnostic accuracy. Materials and Methods： 57 cases with parotid pleomorphic adenoma and adenolymphoma were proved by operation and pathology. We analysed ultrasound imaging characteristics by 2D and CDFI examination. Results： 57 cases （42 cases of pleomorphic and 15 cases of adenolymphoma） were examined by 2D and CDFI, the accuracy rate were 93%. Although Typical sonography of parotid pleomorphic adenoma and adenolymphoma have their characteristic imagings respectively, nontypical sonography of them have some similar features. Conclusion： Ultrasounds detective rate of parotid mass was 100%.Ultrasound is the first choice in diagnosing parotid masses. By observing and analyzing through CDFI, press and touch the masses carefully with probe ,differential diagnosis will be effectively.
