摘　　要：目的 :探讨鼻咽癌放疗后腔外肿块残留或复发的MR特点。方法 :回顾性分析了鼻咽癌放疗后鼻咽腔无肿块、腔外肿块存留或复发的 2 0例MR检查资料。结果 :咽旁间隙肿块 11例 ;颅底骨质破坏 17例 ;海绵窦受侵犯 11例、后颅窝肿块 3例 ;眼眶侵犯 2例 ;副鼻窦及鼻腔异常 15例 ;放射性脑病 4例。结论Objective:To study the MRI charicteristics of extracav ity residual masses and relapse in nasopharyngeal carcinoma after radiotherapy.Methods:20 cases were selected,with them there were no mas ses in the nasopharyngeal cavity,but extracavity residual masses and relapsed af ter radiotherapy.Results:The results were 11 cases with pa rapharyngeal space masses;17 cases with destruction of skull base;11 cases with invasion of cavernous sinus;3 patients with masses in the posterior cranial foss a;2 cases with invasion of the orbits;15 cases with abnormality of paranasal sin us and nasal cavity and 4 cases with radiation encephalopathy. Conclusion:MRI is a effective method to find extracavity r esidual masses and relapse at nasopharyngeal carcinoma after radiotherapy. [
