Patient subsequently underwent pre-surgical embolization of the mass. Conventional angiographic images (a) after selection of the left common carotid artery demonstrate an intense tumor blush (white arrowhead) arising between the left internal and external carotid arteries (white arrows). Subsequent images post particle embolization (b) of the tumor demonstrate marked interval decrease in tumor blush, with only a small residual portion of blush (black arrow) along the proximal ECA. Final pathology was consistent with a carotid body paraganglioma
