摘　　要：目的:总结彩色超声多普勒(CDFI)与数字减影血管造影(DSA)在颈动脉体瘤与神经鞘瘤诊断与鉴别诊断中的影像学特征。方法:对1990年1月～2005年12月收治的8例颈动脉体瘤和14例神经鞘瘤患者进行CDFI与DSA检查,对其影像学特征进行比较。结果:颈动脉体瘤的CDFI和DSA特征为:颈总动脉分杈处单发性肿块,并与其紧密相连,瘤体内血流极为丰富,瘤体使颈外动脉向前内移位、颈内动脉向后外移位,颈内、外动脉分杈角度增大明显,DSA呈高脚杯状改变;神经鞘瘤紧邻颈动脉,颈总动脉分杈处角度无改变,瘤体内血流信号不丰富,瘤体使颈动脉向前、外移位。结论:颈动脉体瘤与神经鞘瘤均有明确的影像学特征,CDFI及DSA在两者的诊断与鉴别诊断方面具有重要的临床实用价值。PURPOSE： To summarize the clinical imaging features of color Doppler flow imaging （CDFI）, digital substraction angiography （DSA） in diagnosis and differential diagnosis between carotid body tumor （CBT） and neurilemmoma. METHODS： The clinical data of 8 patients with CBT and 14 patients with neurilemmoma treated in our hospital from 1990 to 2004 were retrospectively compared with CDFI and DSA. RESULTS： The imaging features of CBT were masses located at the bifurcation of the carotid artery, with abundant blood supply in the tumor, the internal and external carotid arteries shifted, the bifurcation of the carotid artery increased like goldcup in DSA. The imaging features of the neurilemmoma were masses located behind the bifurcation of the carotid artery, and the carotid bifurcation was normal, no blood supply in the tumor, but carotid arteries shifted. CONCLUSIONS： CBT and neurilemmoma have their own imaging characteristics in CDFI and DSA. Both CDFI and DSA have important values in diagnosis and differential diagnosis between CBT and neurilemmoma.
