Congenital External Carotid Artery Aneurysm

An 8-month-old child presented with a right pulsatile neck mass. The tumor's rapid increase in size and respiratory problems prompted image evaluation. An external carotid artery aneurysm was found, which was compressing other neck structures. The patient underwent aneurysm resection and ligation at its insertion on the common carotid artery. Recovery was uneventful and no further aneurysms on other arteries were found.
