case_images: CT angiography of the neck with axial (a), coronal (b), and sagittal (c) sections of the heterogeneously enhanced irregular 2.4 x 2.2 x 2.2 cm mass within the right carotid sheath. The green arrows refer to the neck mass.

case_images: 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)).
case_images: MRI, axial section, fast spoiled gradient echo with contrast. The green arrow refers to the neck mass.

case_images: 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).
case_images: MRI, coronal section, T1-weighted with fat saturation and contrast. The green arrow refers to the neck mass.
