目的：为了提高ＣＴ对鼻咽病变鉴别的认识。方法：本文收集６３例鼻咽有病变者，其中鼻咽癌４６例，恶性肉芽肿４例，纤维血管瘤３例，结核２例，非何杰金氏淋巴瘤１例，慢性炎症７例，全部病例作鼻咽轴位ＣＴ平扫，３例纤维血管瘤加作增强扫描，详细地分析了其临床和ＣＴ表现。结果：鼻咽癌病人头痛和颈部淋巴结转移出现率较高，分别为３７．０％和５６．５％，且早期即向深层浸润生长；恶性肉芽肿有特征性的恶臭，病变呈中线性生长，愈向鼻咽深层，病变愈轻；纤维血管瘤肿块呈紫红或灰红色，增强检查肿块轮廓清楚，强化明显；结核和慢性炎症虽有顶后壁增厚，但咽缝存在；非何杰金氏淋巴瘤在鼻咽部形成大的肿块，腹腔和后纵隔淋巴结广泛肿大。结论：根据临床表现，结合ＣＴ特征，大多数鼻咽病变可作出正确诊断。
Objective: To improve the recognition of nasopharyngeal lesions by CT. Methods: We collected 63 cases of nasopharyngeal lesions, including 46 cases of nasopharyngeal carcinoma, 4 cases of malignant granuloma, 3 cases of fibrosarcoma, 2 cases of tuberculosis, 1 case of non-Hodgkin’s lymphoma, 7 cases of chronic inflammation, All cases were taken CT scan of nasopharynx, three cases of fibro-hemangioma with enhanced scan, and the clinical and CT findings were analyzed in detail. Results: The incidence of headache and cervical lymph node metastasis in patients with nasopharyngeal carcinoma were higher (37.0% and 56.5%, respectively), and they were infiltrated into the deep layers in early stage. Malignant granulomas had characteristic stench and the pathological changes were linear Growth, the more deep nasopharynx, the lesser the lesion; hemangioma tumor was purple or gray red, enhanced examination of the clear outline of the mass, enhanced significantly; although tuberculosis and chronic inflammation of the posterior wall thickened, but the pharyngeal seams exist; non-what Jie Jin Lymphoma in the nasopharynx formed large lumps, abdominal cavity and posterior mediastinal lymph nodes are widely enlarged. Conclusion: According to clinical manifestations and CT features, most nasopharyngeal lesions can be correctly diagnosed.
