Figure 1.
Figure 1. Computed tomography angiography (CTA) of the neck, coronal section, shows 4.9 × 3.4 × 4.5 cm enhancing mass at the carotid artery bifurcation (a) with mass effect on the right internal jugular vein and right airway (b). The carotid arteries are displaced as well.
Figure 2.
Figure 2. Computed tomography angiography (CTA) of the neck with and without contrast, axial section, shows an enhancing mass in the right side of the neck with mass effect on the right airway (blue arrows).

Figure 5. Schematic diagram of the Shamblin grouping of CBTs into I, II, III and IIIb. It is basically based on the relationship between the tumor and the carotid arteries. The intersected lines are the X and XII nerves which are closely related to the tumor. This diagram was adopted from Reference [18].
