摘　　要：目的:通过影像学分析,探讨64排螺旋CT(64-MSCT)、CT血管造影(CTA)在颈动脉体瘤和神经鞘瘤诊断和鉴别诊断中的应用。方法:对2006-03—2008-07来我院就诊的5例颈动脉体瘤和11例颈部神经鞘瘤患者进行64-MSCT及CTA检查,并对其影像学特征进行分析。结果:64-MSCT、CTA图像可清楚显示颈动脉体瘤和神经鞘瘤的影像学特征。64-MSCTA重建图像清晰,可直观、立体、多角度地显示肿瘤与颈内、外动脉的关系。颈动脉体瘤位于颈动脉分叉处,肿瘤使颈内、外动脉移位,颈内、外动脉夹角变大,呈典型的"杯口状"影像。神经鞘瘤位于颈动脉的深面,肿瘤使颈动脉向前、外移位,颈总动脉分叉角度无明显改变,肿瘤与颈动脉无粘连。结论:颈动脉体瘤与神经鞘瘤具有不同的影像学特征,64-MSCT、CTA在颈动脉体瘤及神经鞘瘤诊断与鉴别诊断中具有重要的临床价值。Objective： To evaluate the medical imagings of 64-MSCT（multi-slice spiral CT） and CTA（CT angiography） in identifying carotid body tumor and neurilemmoma. Methods： 5 patients with carotid body tumors and 11 patients with neurilemmomas were examined by 64-MSCT and CTA from March 2006 to July 2008, their images were analyzed retrospectively. Results： The differential imageology of carotid body tumors and neurilemmomas had been clearly shown by 64-MSCT and CTA. The images performed by 64-MSCTA might clearly and directly reveal the relationship between tumor and carotid artery. The carotid body tumors located at the bifurcation of the carotid artery usually caused the internal and external carotid arteries shifted, and the angle between the two arteries became enlarged, just like ＂gold cup＂. The neurilemmomas usually located behind the carotid artery; the carotid artery was pushed forwardly and laterally by the tumor. The angle between external and internal carotid artery didn＇t change obviously, and a space between the tumor and carotid artery was observed. Conclusion： The carotid body tumor and neurilemmoma have their radiological features in 64- MSCT and CTA respectively. 64-MSCT and CTA may be applicable in the differential diagnosis of carotid body tumor and neurilemmoma.
