摘要
目的 :探讨鼻咽部良、恶性病变的 CT表现及鉴别诊断。方法 :分析 90例鼻咽部病变的 CT资料 ,讨论良、恶性病变的 CT特征。结果 :1恶性病变 5 7例 ,其中鼻咽癌 5 5例 ,淋巴瘤 2例 ,恶性病变表现为咽隐窝膨隆突出、顶后壁增厚或形成肿块 ,周围结构侵犯主要有咽缝或咽旁间隙变窄、模糊、消失 ,颈部淋巴结肿大 ,颅底骨质破坏等。淋巴瘤多不侵犯颅底骨质。 2良性病变 33例 ,为单纯的咽隐窝膨隆或后顶壁增厚 ,病变边界多较清楚 ;颈前肌前缘可模糊 ,后缘清楚 ;不侵犯咽旁间隙及咽缝。结论 :CT检查对鼻咽部良。
Objective:To study the CT findings and differential diagnosis of benign and malignant nasopharynx diseases Methods:90 cases'CT materials of nasopharynx diseases were analyzed and the CT features of benign and malignant diseases were discussed Results:①There were 57 cases of malignant diseases,of which 55 were nasopharyngeal carcinoma(NPC),2 cases were lymphoma.The CT findings were thickening of superio posterior wall,swelling of pharyngeal recess or forming masses,coexisted with one or more items of the following malignant signs:nasopharyngeal raphe or parapharyngeal space narrowing,fading or disappearing;neck lymph node enlarging,destruction of the bone of skull base and so on.Lymphoma did not invade the bone of skull base.②CT findings of 33 cases of benign diseases were purely swelling of pharyngeal recess or thickening of superio posterior wall,the boundary of the diseases were clear,the front edge of the precervical muscle became blur but the back edge were clear.the diseases did not invade parapharyngeal space and nasopharyngeal raphe Conclusion:CT examination has significant value in diagnosis of benign and malignant disease of nasopharyngeal region
