The first case of vagal body tumor in Japan was reported. A 49-year-old woman complained of hoarseness for five years. A firm mass which was deeply located behind the left angle of the mandible was recognized. The left faucial tonsil was displaced forward and the left walls of the epipharynx, mesopharynx and hypopharynx were swollen by the parapharyngeal tumor. Paralysis of the left X and XII nerves was also noted. X-ray (axial position) and C-T scan demonstrated tumor shadow below the left floor of the middle cranial fossa. No destructive change in the cranial and other bones was observed. Carotid angiogram revealed that the tumor was of high vascularity and that the bifurcation of the carotis was not widened. The tumor was removed by radical neck dissection, combined with simple mastiodectomy and removal of the styloid process, by which the base of skull, foramen stylomastoideum and foramen jugulare were exposed. The carotis interna was ligated because the tumor was very vascular and firmly adherent to the surface of the vessel, but no serious complications followed. The resected tumor was well encapsulated, measuring 6×3×3cm. No evidence of recurrence has been found up to the present. We considered that carotid angiography was the most important examination for the diagnosis of vagal body tumor.
