| 摘 要 目的 分析颈动脉体瘤及颈静脉球瘤的超声特征表现，探讨超声对其诊断价值。方法 结合文献复习，回顾分析经病理确诊的10例颈动脉体瘤及1例颈静脉球瘤的超声特征表现并评价超声对其诊断率。结果 颈动脉体瘤的超声表现为位于颈动脉分叉处的低回声实性团块，使颈内动脉与颈外动脉间距增宽，夹角增大，团块内可见高速低阻的丰富血流信号，上述表现具有特征性，超声诊断率较高；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，超声难以明确诊断，但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，可作为本病首选的诊断技术；颈静脉球瘤的超声变现具有一定的特征性，超声虽然难以确诊但可为本病的手术治疗提供有效信息。 |

| ABSTRACT Objective To analyze the sonographic features of carotid body tumors and glomus jugulare tumor and explore the clinical value of ultrasound in the diagnosis of cervical paraganglioma. Methods Combined with literature review, we reviewed the sonographic features of 11 cases of neck paraganglioma confirmed by pathology (including 10 cases of carotid body tumors and 1 case of glomus jugulare tumor) and evaluated the value of ultrasound in the diagnosis of cervical paraganglioma. Results The sonographic findings of carotid body tumor were hypoechoic solid mass located in the carotid bifurcation, which made the distance of internal carotid artery and external carotid artery widen and angle increase. The mass had forms rule and abundant blood flow signals with high speed and low resistance. These sonographic performance were characteristic and the diagnostic rate was high. 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 could clearly show the anatomic relationship between the mass and the internal jugular vein wall. Conclusions 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. |
