CT angiography of the neck demonstrated a heterogeneously enhanced irregular 2.4 x 2.2 x 2.2 cm mass within the right carotid sheath along the lateral aspect of the proximal internal and external carotid arteries with minimal splaying of these arteries (Figures 1(a), 1(b), and 1(c)).
MRI, axial section, fast spoiled gradient echo with contrast. The green arrow refers to the neck mass.

MRI displayed a 2.5 x 1.9 x 3 cm mass extending from the inferior margin of the right carotid to the level of the piriform sinuses within the carotid sheath which was intensely enhanced following contrast administration (Figures 2 and 3).
MRI, coronal section, T1-weighted with fat saturation and contrast. The green arrow refers to the neck mass.
