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、恶性病变的诊断有重要价值
Objective: To investigate the CT findings and differential diagnosis of benign and malignant nasopharyngeal lesions. Methods: CT data of 90 cases of nasopharyngeal lesions were analyzed to discuss CT features of benign and malignant lesions. Results: A malignant lesions in 57 cases, of which 55 cases of nasopharyngeal carcinoma, lymphoma in 2 cases, the performance of malignant lesions protruding crypt swallowed, the posterior wall thickening or the formation of mass, the main structure around the violations of the pharyngeal or pharynx Side of the gap narrowing, blurred, disappear, neck lymph nodes, skull base bone destruction. Lymphoma does not violate the skull base. 2 benign lesions in 33 cases, simple throat crypt bulging or posterior parietal thickening, more clear boundaries of the lesion; Anterior cervical muscle front can be fuzzy, trailing edge clear; does not violate the parapharyngeal space and pharyngeal suture. Conclusion: CT examination of nasopharyngeal benign and malignant lesions of great value
