目的:讨论喉癌的 CT 表现及 CT 在评价喉癌浸润范围上的作用。材料与方法:对经临床病理证实的30例喉癌作回顾性分析,其中手术25例。术后整块喉癌连续大切片15例。结果:声门上癌13例(43.33%),声门癌5例(16.66%),跨声门癌12例(40%)。9例累及会厌前间隙和喉旁间隙,4例侵犯前联合,5例侵犯喉软骨,22例(73.33%)有颈淋巴转移,其中累及颈动脉19例(86.36%),淋巴结肿大伴有中心坏死7例(31.82%)。结论:CT 在判断喉癌的浸润范围上简单易行,准确可靠,但对淋巴结及软骨破坏的判断上仍有一定的局限性。
Objective: To discuss the CT findings of laryngeal carcinoma and the role of CT in assessing the extent of laryngeal carcinoma infiltration. Materials and Methods: Retrospective analysis of 30 cases of laryngeal carcinoma confirmed by clinical pathology, including 25 cases of surgery. Fifteen consecutive large slices of laryngeal cancer after operation. Results: There were 13 cases of supraglottic carcinoma (43.33%), 5 cases of glottic carcinoma (16.66%) and 12 cases of transglottic carcinoma (40%). Nine cases involved the anterior epiglottis space and the parapharyngeal space, 4 cases had anterior commissure, 5 cases had laryngeal cartilage invasion, 22 cases (73.33%) had cervical lymphatic metastasis, of which 19 cases (86.36%) involved the carotid artery and enlarged lymph nodes with center Necrosis in 7 cases (31.82%). Conclusion: CT is simple, accurate and reliable in judging the invasion of laryngeal carcinoma, but there are still some limitations on the judgment of lymph node and cartilage destruction.
