目的：评估鼻咽癌的 ＣＴ表现及其临床价值。材料与方法：有病理组织学诊断的鼻咽癌 ９６例。 ＣＴ以 ＯＭ线或平行于颅底线向下常规扫描至硬腭水平，部分病例根据临床需要，扫描至颈段水平。结果：９６例中，鼻咽腔变形狭窄７２例。鼻咽部全部受侵，其中全壁受侵１０例，顶后壁３４例，右侧壁２９例，左侧壁２３例。脂肪垫受侵８４例。咽旁间隙改变为狭窄４８例，移位２３例，消失２０例。颅底骨质受侵４１例。副鼻窦受累２９例，鼻道８例，乳突炎１２例，突眼２例。颈部淋巴结转移５９例。结论：ＣＴ对鼻咽癌的诊断是有价值的，尤其是对肿瘤侵犯部位及范围较为明确。
Objective: To evaluate the CT findings and clinical value of nasopharyngeal carcinoma. Materials and Methods: There are 96 cases of nasopharyngeal carcinoma diagnosed by histopathology. CT to OM line or parallel to the skull base line down to the level of the normal hard palate, some cases based on clinical needs, scanning to the level of the cervical segment. Results: Of the 96 cases, 72 had nasopharyngeal strictures. Nasopharyngeal all invaded, including 10 cases of whole wall invasion, 34 cases of the top posterior wall, 29 cases of the right side wall and 23 cases of the left side wall. 84 cases of fat pad invasion. Parapharyngeal space was changed to stenosis in 48 cases, 23 cases of displacement, disappeared in 20 cases. 41 cases of skull base bone invasion. Nasal sinus involvement in 29 cases, 8 cases of nasal passages, mastoiditis in 12 cases, exophthalmos in 2 cases. Neck lymph node metastasis in 59 cases. Conclusion: CT is valuable for the diagnosis of nasopharyngeal carcinoma, especially for the site and extent of tumor invasion.
