颈动脉体瘤属于颈部副神经节瘤,又称为化学感受器瘤,发病率较低。颈动脉体瘤的影像学表现国内文献报道较少,本文通过分析6例经病理证实的颈动脉体瘤CT和MRI表现,旨在总结其影像学诊断要点,提高诊断和鉴别诊断水平。1材料和方法收集2002—2004年经病理证实的颈动脉体瘤6例。其中 Carotid body tumor belongs to the cervical paraganglioma, also known as chemosensory tumor, the incidence is low. The imaging findings of carotid body tumor are few reported in the country. Through analyzing the CT and MRI manifestations of 6 carotid body tumors confirmed by pathology, this paper aims to summarize the main points of imaging diagnosis and improve the diagnostic and differential diagnosis. 1 Materials and Methods collected from 2002 to 2004 pathologically confirmed carotid body tumor in 6 cases. among them
