超声诊断颈动脉体瘤和颈静脉球瘤的应用价值

Value of ultrasound in diagnosis of carotid body tumors and glomus jugulare tumor

目的分析颈动脉体瘤和颈静脉球瘤的超声表现特征,探讨超声诊断该病的临床应用价值。方法回顾性分析经病理确诊的10例颈动脉体瘤和1例颈静脉球瘤的超声表现特征。结果颈动脉体瘤超声表现均为位于颈动脉分叉处的实性团块状低回声,边界清晰,团块内可见高速低阻的丰富血流信号;其中9例肿瘤生长将颈内动脉与颈外动脉撑开,使颈内动脉与颈外动脉间距增宽,夹角增大。颈静脉球瘤超声表现为颈静脉孔区的条状低回声实性团块,向下延续至颈内静脉内,团块内可见高速低阻的丰富血流信号,超声可清晰显示肿块与颈内静脉管壁的解剖关系。结论颈动脉体瘤的超声表现具有较高的特征性,超声可作为本病首选的诊断技术;颈静脉球瘤的超声表现具有一定的特征性,超声虽难以确诊但可为本病的手术治疗提供有效信息。

Objective To analyze the sonographic features of carotid body tumors and glomus jugulare tumor,and to explore the clinical diagnostic value of ultrasound.Methods The sonographic features of 10 cases of carotid body tumors and 1 case of glomus jugulare tumor were analyzed retrospectively.Results The sonographic findings of carotid body tumor were hypoechoic solid mass located in the carotid bifurcation.The mass had rule form and abundant blood flow signals with high speed and low resistance.9 cases were located in the carotid bifurcation,which made the distance of internal carotid artery and external carotid artery widen and angle increase.The sonographic findings of glomus jugular tumor were hypoechoic solid mass located in the jugular foramen and elongated into the internal jugular vein.The mass also had abundant blood flow signals with high speed and low resistance.Ultrasound showed the anatomic relationship between the mass and the internal jugular vein wall.Conclusion Ultrasonography has high diagnostic value for carotid body tumor and can be used as the preferred technology.Glomus jugular tumor has certain characteristic ultrasonic performance and ultrasound can provide effective information for the surgical treatment though it is hard to make a definite preoperative diagnosis.
