The value of preoperative embolization is well established in the management of paragangliomas. Percutaneous direct intratumoral embolization has been described as a safe and effective technique to achieve devascularization of these tumors, thereby reducing intraoperative blood loss. However, the present article presents a case in which a patient developed vocal cord palsy after percutaneous embolization of a vagal paraganglioma. In view of the present findings, the possibility of intraoperative nerve monitoring needs to be explored to ensure safety of this procedure.
