An Unusual Case of Laryngeal Paraganglioma in a Patient with Carotid Body Paraganglioma: Multimodality Imaging Findings

Figure 5

A lateral cervical angiogram from the left common carotid artery demonstrates the intense blush at the carotid bifurcation corresponding to the carotid body paraganglioma (a). Right common carotid artery lateral cervical angiogram shows significant tumor vascularity (arrow) at the larynx (b). Principal arterial feeder to the tumor from superior thyroid artery. Significant reduction is seen in tumor vascularity after embolization of the ascending pharyngeal and proximal occipital artery with polyvinyl alcohol particles measuring 255 to 350 (c). Superselective catheterization of the superior thyroid artery after embolization shows complete devascularization (d).
