Where does carotid body tumor arise from?

Carotid body paragangliomas arise at the bifurcation of the internal and external carotid arteries and have classic radiographic features. Carotid body paragangliomas are vascular lesions, and this is reflected in their imaging appearance.

How fast do carotid body tumors grow?

They are slow-growing tumors that can remain asymptomatic for many years. The doubling time (TD) of carotid body tumors (CBTs), as estimated by Jansen et al using sequential imaging, was 7.13 years with a median growth rate of 0.83 mm/year.

Where does a carotid body tumor originate from?

Color Doppler demonstrates significant internal vascularity within the mass in about 75% of all carotid body tumors. The feeders arise from the external carotid artery, although the internal carotid and the vertebral artery may also supply the carotid body tumor. 5.On spectral analysis, low resistance flow may be detected within the mass.

What to do if you have a carotid tumor in your head?

Your doctor will closely examine your head and neck to check for signs of a carotid body tumor. You may need tests, such as: Ultrasound – a test that uses a special tool (transducer/wand) that sends sound waves inside your body to create pictures.

What are the risks of carotid tumor removal?

One possible complication is stroke, but this is rare and happens in less than 2% of carotid body tumor removals. The risk is highest for patients who have large tumors and need to have vascular repair or replacement.

How can you tell if a carotid tumor is internal or external?

The mass is seen classically in close proximity to the carotid bifurcation, widening the bifurcation and splaying the vessels. It may also appear to compress or encase the common, external and/or internal carotid vessels. 4. Color Doppler demonstrates significant internal vascularity within the mass in about 75% of all carotid body tumors.
