Objective: To explore and analyze the significance of color Doppler ultrasound in the differential diagnosis of cervical schwannomas and carotid body tumors.
Methods: From May 2010 to May 2012, 24 cases were treated in our hospital. 11 cases of cervical schwannomas and 13 cases of carotid body tumors were confirmed by surgery. We retrospectively analyzed the color Doppler ultrasound images of all cases.
Results: The schwannomas were single-shot, substantially hypoechoic cysts, which were round and had an envelope, clear borders, and internal wired blood flow signals. The arterial blood flow spectrum belonged to high-resistance type; Single or double masses appear in the bifurcation of the common carotid artery of carotid body tumor cases. The blood flow in the tumor is abundant. The external carotid artery was squeezed forward and internal shifted by the tumor while the internal carotid artery squeezed backward and external shifted. The arterial blood flow spectrum belonged to Low resistance spectrum.
Conclusion: Both carotid body tumors and cervical schwannomas have specific imaging characterization. Color Doppler ultrasound has very important clinical application practical value on the differential diagnosis of cervical schwannomas and carotid body tumors.
