目的 探讨颈动脉体瘤的ＣＴ多平面成像表现。方法 对８例经手术病理证实为颈动脉体瘤的临床资料进行回顾性分析。治票８个颈动脉体瘤均位于颈动脉分叉水平，术前行ＣＴ平扫和高分辨ＣＴ增强扫描并行多平面成像（ＭＰＲ）处理。ＣＴ平扫表现为软组织密度肿块，呈圆形或卵圆形，边缘清楚，增强扫描肿瘤明显强化，ＭＰＲ显示颈动脉分叉扩大，其中２例肿瘤向上侵犯颅底并经颈静脉孔侵入颅后窝桥小脑角区。结论 高分辨ＣＴ增强扫描加多平面成像是诊断颈动脉体瘤及其周围侵犯关系的安全、可靠的检查方法之一。
Objective To investigate the CT multiplanar imaging of carotid body tumor. Methods The clinical data of 8 patients with carotid body tumor confirmed by surgery and pathology were retrospectively analyzed. All the eight carotid body tumors were treated at the bifurcation level of the carotid artery. Preoperative CT scan and high resolution CT enhanced scan were performed in parallel multiplanar imaging (MPR). CT scan showed soft tissue density mass, circular or oval, clear edge, enhanced scan enhanced significantly, MPR showed the bifurcation of the carotid artery enlargement, of which 2 cases of tumor upside down the skull base and jagged through the jugular foramen Sacral cerebellar angle area. Conclusion High-resolution CT enhanced scan plus multiplanar imaging is one of the safe and reliable methods to diagnose the relationship between carotid body tumor and its surrounding.
