Abstract

Palpable mass around the carotid artery are included aneurysm, pseudoaneurysm, carotid body tumor as a pulsating mass and schwannoma as a non-pulsatile mass. A schwannoma is a nerve sheath tumor and there was no specific identified cause. Most of the schwannoma in the neck is originated from 9th to 12th cranial nerve or sympathetic ganglion. Carotid body tumor shows hypervascularity compare to hypovascularity in schwannoma. We reported a case of schwannoma which could be diagnosed with duplex ultrasonography.
