| Abstract;Resection of a neurogenic tumor in the neck leads to paralysis of the nerve, so it is important to recognize its origin before operation. Most patients complain of only neck mass, so relationship of location among the tumor, the common or internal carotid artery and the internal jugular vein were investigated with CT scans and MR images. Six neurogenic tumors were treated and examined together with twenty-three cases from literature. Vagus nerve origin was found in fifteen cases, sympathetic chain in the neck was found in eleven casses and hypoglossal nerve was found in three cases. The angle at the center of the carotid artery, tumor and jugular vein were taken. This study revealed the tumor originated in the vagus nerve separating these vessels and the angle was more than 90.DEG.. While in the sympathetic chain tumor, the angle was less than 90.DEG. and it displaced the carotid artery and jugular vein anterolaterally. The hypoglossal neurogenic tumor did not separate these vessels and displaced them posteriorly. In conclusion, to clarify the origin of neurogenic tumor, it is important to determine the location and angle of the tumor, carotid artery and jugular vein with CT scanning or MR imaging.
