目的分析总结颈动脉体瘤(CBT)多层螺旋CT血管成像(MSCTA)的表现,并探讨其诊断价值。资料与方法回顾性分析总结16例(20个病灶)经病理证实的CBT患者的MSCTA资料。结果(1)16例中3例为双侧发病,其余为单发,部分病例合并颈静脉球瘤和动静脉畸形。(2)病灶大小为0.7 cm×1.2 cm×1.3 cm～6.3 cm×4.8 cm×7.1 cm。(3)密度不均者4例,1例发生坏死囊变,除发生囊变区外均明显强化。(4)病灶位于颈动脉分叉处14例,呈典型的“高脚酒杯征”。(5)所有脑动脉CTA均显示为正常。结论MSCTA能显示CBT的特点及其与周围血管、组织结构的关系,是CBT的有效诊断方法。
Objective To analyze and summarize the performance of multislice spiral CT angiography (MSCTA) of carotid body tumor (CBT) and to explore its diagnostic value. Materials and Methods Retrospective analysis of MSCTA data of 16 pathologically confirmed CBT patients was performed in 16 patients (20 lesions). Results (1) Three of the 16 cases were bilateral and the others were single. Some cases were complicated with jugular vein tumor and arteriovenous malformation. (2) The size of the lesion was 0.7 cm × 1.2 cm × 1.3 cm ~ 6.3 cm × 4.8 cm × 7.1 cm. (3) There were 4 cases of uneven density, 1 case of necrotic cystic degeneration, except cystic area were significantly enhanced. (4) Focal lesions were located in the bifurcation of the carotid artery in 14 cases, showing a typical (5) All cerebral arteries CTA showed normal. Conclusion MSCTA can show the characteristics of CBT and its relationship with the surrounding blood vessels and tissue structure, which is an effective diagnostic method for CBT.
