目的 分析颈动脉体瘤的灰阶及彩色多普勒超声图像特征 ,以提高诊断的准确率。方法 回顾性分析 18例颈动脉体瘤灰阶超声及其中 11例彩色超声的图像资料 ,并与易引起误诊的多种病变作对比分析。结果 B超显示肿块均位于颈动脉分叉处 ,边界清楚 ,内回声略低 ,较均匀 ,常包绕颈总、内、外动脉 ,颈动脉夹角增宽 ,肿瘤内血流丰富 ,均为动脉。 17个颈动脉体瘤超声诊断正确 ,其诊断准确率为 94 .4 %。结论 超声检查是颈动脉体瘤安全。
Objective To analyse the findings of gray scale and colour Doppler sonography for carotid body tumor and to improve the sonographic diagnostic accuracy. Methods A retrospective review was performed of sonographic material of 18 carotid body tumors by gray scale sonography and 11 by colour Doppler sonography, with comparison with other diseases which are frequently misdiagnosed as carotid tumor. Results Well defined, even weakly hypoechoic masses were noted on gray scale ultrasonogram at the carotid bifurcation, commonly broadening the carotid bifurcation and often encasing the common, external and internal carotid arteries. Disorderly non echoic channel like structures in the tumor were sometimes observed. Colour Doppler sonography showed abundant flow in the tumor.The non echoic channel like structures were vascularities. Seventeen masses diagnosed by ultrasound were proved to be carotid body tumors. The other one was confirmed as a neurogenic tumor, giving an accuracy rate of 94.4% for sonographic diagnosis. Conclusion Sonographic examination of the carotid body tumor is highly accurate. It is safe and reliable.
