目的探讨喉癌的薄层CT表现及临床诊断价值。方法回顾性分析50例经手术及病理证实的喉癌患者的薄层CT表现,判断肿瘤侵犯喉部结构的情况。结果病变部位位于声门31例,声门上15例,声门下部2例,跨声门2例。会咽前间隙受侵17例,声门旁间隙受侵26例,前联合受累24例,喉软骨侵犯8例,颈部淋巴结肿大10例,远处转移2例。结论薄层CT扫描可清晰显示肿块的形态位置、侵犯的范围及颈部淋巴结转移,能对喉癌诊断和治疗提供重要信息。
Objective To investigate the lamellar CT findings and clinical diagnostic value of laryngeal cancer. Methods The CT findings of 50 cases of laryngeal carcinoma confirmed by surgery and pathology were retrospectively analyzed to judge the invasion of laryngeal structure by tumor. Results The lesion was located in 31 cases of glottis, 15 cases of glottis, 2 cases of lower part of glottis, 2 cases of trans-glottic door. There were 17 cases of anterior pharyngeal space invasion, 26 cases of supraglottic anastomosis, 24 cases of anterior combined involvement, 8 cases of laryngeal cartilage invasion, 10 cases of cervical lymph node enlargement and 2 cases of distant metastasis. Conclusion The thin-slice CT scan can clearly show the shape and location of the mass, the scope of invasion and lymph node metastasis of the neck, which can provide important information for the diagnosis and treatment of laryngeal cancer.
