摘要
To the Editor： Carotid body tumor （CBT） is a highly vascular neoplasm of neural crest origin arising in paraganglial cells of the carotid bifurcation. Branches from external carotid artery or glomic artery arising at the bifurcation of common carotid artery dominate in the blood supply mode. Only very few cases with supplementary blood supply from an internal carotid artery （ICA） have been reported in literature, but were still short of imaging proof Here, we report an extremely rare case of CBT with blood supply from 1CA, which had been performed 4 times of unaccomplished surgical explorations before the tmnor was excised during the 5th time of surgery. She also presented carotid sinus syndrome that was also extremely rare among CBT patients.
