A HEALTHY 73-year-old woman was seen for a slowly enlarging right cervical mass located near the angle of her mandible. She had symptoms of fever, chills, and hoarseness. Physical examination demonstrated a firm, nontender, pulsatile mass without associated lymphadenopathy. A bruit was present over the mass on auscultation. A computed tomography scan was performed, showing a 3 × 2-cm mass located between the external and internal carotid arteries (ICA) that enhanced with intravenous contrast injection (Figure 1). The mass was partially wrapped around the ICA. There was no evidence of invasion into the surrounding tissues, nor was there a mass in the contralateral neck. A cerebral arteriogram showed "splaying" of the external carotid artery and the ICA, with blushing seen on delayed images (Figure 2).
