Abstract:
OBJECTIVE To describe the sonographic features of carotid body tumor(CBT), and determine the utility of ultrasonography as a diagnostic study in the preoperative patients. METHODS Sonograms of 60 patients with 65 CBT were reviewed with gray scale and duplex Doppler sonography. The evaluated features included the location, size, margins, shape, internal echogenicity, the relationship between the tumor and the carotid artery,and blood flow velocity. RESULTS All carotid body tumors were located at the carotid artery bifurcation. Well-defined, solid, weakly hypoechoic masses were noted on gray scale sonography in the carotid bifurcation. Color Doppler sonography showed hypervascularity in 61 masses. Pulsed Doppler analysis of blood flow within the tumor mass was possible in 61 CBT, and low-resistance waveforms were obtained from multiple sites within the mass in all cases. CONCLUSION The ultrasound characteristics of the CBT possess specificity to some extent. Duplex Doppler ultrasound can provide the relationship between the tumor and the carotid artery,and provide important information of intratumor blood flow,which has important value in the diagnosis of CBT.
