目的:探讨鼻咽纤维血管瘤的CT表现及对临床诊断的价值。方法:回顾分析经手术和病理证实的16例鼻咽纤维血管瘤的临床与CT表现、诊断及Chandler分期。结果:鼻咽纤维血管瘤CT平扫多表现为等或稍低密度,与周围分界不清,增强扫描肿瘤增强极显著,边界清楚,常伴有骨质受压和吸收,肿瘤侵犯部位按Chandler标准Ⅰ期4例、Ⅱ期3例、Ⅲ期4例、Ⅳ期5例。CT诊断准确率为93.2%。结论:CT对鼻咽纤维血管瘤可作出明确诊断及分期,应作为本病的首选检查方法。
Objective To study the CT manifestations of nasopharyngeal anglofibroma(NPAF) and its value in elinical diagnosis and treatment. Methods 16 case of NPAF were retrospectively analyzed with their CT features,clinical and CT diagnosis and Chandler stage. Results On CT plane scan, NPAF were isodensity or slight hypodensity and could not be differentiated from surrounding tissue. On enhancement CT scan, NPAF were grossly enhanced and could be clearly differentiated from surrounding structures. Most case showed either slight or remarkable pressure and bone destruction over the base of skull. According to Chandler classification,there were 4 cases of stage Ⅰ ,3 cases of stage Ⅱ ,4 cases of stage Ⅲ ang 5 cases of stage Ⅳ, CT diagnosis accurate rate is 93.2%.
