Overview
The combination of B mode ultrasound imaging and color-Doppler sonography has been observed to be diagnostic for carotid body tumor.
Ultrasound
- Two-dimensional ultrasound imaging, by itself, is not diagnostic, however, it may be helpful in the diagnosis of carotid body tumor.[1]
- A solid, well-defined, hypo echoic lesion on ultrasound imaging.
- This tumor also causes the displacement of the nearby structures
- The external carotid artery is usually splayed anteriorly
- The internal carotid artery and internal jugular vein are moved posteriorly.
- On color-doppler ultrasound imaging, the tumor appears hypervascular and the direction of blood flow in the tumor is upward at a greater extent.
- It is of particular note that, although not common, the tumor may not be hypervascular.
- The combination of B mode ultrasound imaging and color-Doppler sonography has been observed to be diagnostic for this tumor.
