| 摘 要： | 目的:探讨腮腺混合瘤声像图特点,为临床诊断提供可靠依据.方法:追踪观察46例(46个)腮腺混合瘤声像图并与术后病理对比分析.结果:46例声像图表现:实质均匀低回声14个占30.4%,实质非均匀低回声21个占45.7%,混合回声7个占15.2%,囊性回声4个占8.7%,根据肿瘤形态是否规则,包膜是否完整,边缘是否整齐与恶性混合瘤发生率做统计学处理(P＜0.01)有显著性差异.46例腮腺混合瘤中12例为恶性,总诊断符合率78.3%.结论:腮腺混合瘤声像图具有某些显著特点,但更重要的是声像图的多样性.超声主要以二维图像特点做综合分析,彩色多谱勒血流显像能在声像图上提供病灶的血管分布和血流信息.

| Abstract: | Objective: To evaluate the ultrasonographic characteristics of mixed tumor of parotid gland,and to supply reliable foundation to clinical diagnosis.Methods: The ultrasonography was performed in 46 cases of mixed tumor of parotid gland,and its findings were contrasted with pathologic results after surgery.Results: In the ultrasonogram of 46 cases,14 cases(30.4%) had mass even low echo,21(45.7%) had mass non-even low echo,7(15.2%) had mixed echo,4(8.7%) had cystic echo.Twelve of 46 cases of mixed tumor of parotid gland were malignant.Ten cases were misdiagnosed,and the accuracy rate of diagnosis was 78.3%.Conclusion: Ultrasonogram of mixed tumor of parotid gland has some significant characteristics. |
