目的探讨螺旋CT在鼻咽癌诊断中的应用。方法收集我院经螺旋CT检查并病理证实后50例鼻咽癌患者,其中放疗前后复查8例。年龄20-70岁,男性32例,女性18例。结果螺旋CT扫描表现为以下情况8例患者咽后璧局部软组织稍增厚局限隆起。8例表现为咽隐窝变平,前后壁融合。18例见肿块向邻近软组织侵犯咽旁间隙不同程度移位、变形,甚至消失,其中3例有淋巴结转移。18例除明显的肿块向周围广泛浸润,向颅内侵犯伴不同程度颅底骨质破坏,其中部分病例有双侧或单侧颈部淋巴结转移。结论螺旋CT对于鼻咽癌诊断、分期、放疗野设计及放疗后复查具有重要价值。
Objective To investigate the application of spiral CT in the diagnosis of nasopharyngeal carcinoma. Methods We collected 50 cases of nasopharyngeal carcinoma after spiral CT examination and pathological examination in our hospital, including 8 cases before and after radiotherapy. Age 20-70 years, 32 males and 18 females. Results Spiral CT scan showed the following cases of 8 cases of rectal biopsy local soft tissue thickening limited uplift. 8 cases showed pharyngeal crypts flattened, anterior and posterior wall fusion. In 18 cases, the tumors were displaced to the adjacent parapharyngeal space by adjacent soft tissue, varying in degrees or even disappearing. Among them, 3 cases had lymph node metastasis. In 18 cases, obvious mass was extensively infiltrated to the surrounding area, and intracranial invasion was accompanied with varying degrees of skull base bone destruction. Some cases had bilateral or unilateral cervical lymph node metastasis. Conclusion Spiral CT is of great value in the diagnosis, staging and radiotherapy field design of nasopharyngeal carcinoma and the review after radiotherapy.
