鼻咽癌癌前病变CT的表现与病理对照分析

The CT and pathologic characteristics in nasopharyngeal precancerous lesion

目的探讨鼻咽癌癌前病变的CT表现,并与鼻咽炎、早期鼻咽癌CT表现进行对比,评价CT诊断鼻咽癌癌前病变的价值。方法从780份临床考虑为鼻咽炎或鼻咽癌患者中,确认35例经鼻咽活检病理证实为鼻咽癌癌前病变的患者,其中26例作CT检查,对照病理结果,重点分析这26份CT图片征象。结果这26例病检诊断为鼻咽癌癌前病变患者中,当时CT报告:鼻咽正常10例;鼻咽炎11例,CT表现鼻咽壁黏膜增粗,软组织增厚,咽隐窝变浅,咽旁间隙变窄;鼻咽癌5例。结论CT对鼻咽癌癌前病变的诊断有一定的价值,但无特征性征象,当发现鼻咽壁局限性黏膜增粗,软组织增厚,咽隐窝变浅,咽旁间隙变窄等,应结合临床做进一步检查或短期内追踪观察。

Objective To explore the CT features of nasopharyngeal precancerous lesion. Methods Among the 780 cases with nasopharyngeal diseases, 35 cases were confirmed by biopsy as nasopharyngeal precancerous lesion and CT examination was performed on 26 cases. Results In the 26 cases with nasopharyngeal precancerous lesion, nasopharyngeal mucosa thicking, soft tissue swelling and pharyngeal recess or parapharyngeal space narrowing were showed on CT. Among those, 10 was reported normal, 11 was reported as nasopharyngitis and only 5 was reported as nasopharyngeal carcinoma. Conclusion The value of CT to nasopharyngeal precancerous lesion is limited. Further examination or short-time follow up should be done when nasopharyngeal mucosa or soft tissue swelling and pharyngeal recess or parapharyngeal space narrowing were observed.
