Abstract
A schwannoma arising from the vagus nerve is relatively uncommon in the neck. In 3 years, 2 patients with a vagus nerve schwannoma were at the Kyoto First Red Cross Hospital. The two patients were 50 and 59-year-old-males. A CT scan showed the tumor between the common carotid artery and the internal jugular vein, and between the internal carotid artery and the internal jugular vein, respectively resulting in an increase in the distance between the artery and the vein (separation). Both patients underwent complete removal of the tumor using an external approach following a CT preoperative diagnosis of a neurilemmoma of the vagus nerve.
A discussion was then made on clinical problems related to the diagnosis including FNA (fine needle aspiration cytology).
