| 摘 要： | 目的:探讨鼻咽纤维血管瘤的CT和MRI影像特点。方法:回顾性分析17例鼻咽纤维血管瘤CT和MRI资料,对肿瘤的侵犯范围、大小、边界、密度或信号、周围骨质改变等进行观察分析。结果:鼻咽部软组织肿块;大部分边界清楚;密度或信号均匀;翼腭窝的扩大增宽,上颌窦后壁受压前移、塑形,但后壁骨质无破坏是其特征性表现;周围骨质的压迫塑形或吸收破坏;显著强化。结论:CT、MRI扫描相结合更有助于肿瘤诊断、定位及分期。术前行DSA有助于了解肿瘤血供,制定合理的治疗方案。

| Abstract: | Objective:To analyze the CT and MRI manifestations of nasopharyngeal angiofibroma.Methods:17 cases of nasopharyngeal angiofibroma were retrospectively analyzed according to the location,size,margin,density or signal of the tumor,and the changes of surrounding bones.Results:The CT and MRI showed a nasopharyngeal mass with well-defined margin,uniform density or signal and remarkably enhanced.The sphenomaxillary fossa was enlarged and the posterior wall of maxillary sinus was compressed and displaced without b... |
