目的：探讨ＣＴ 对喉咽癌的诊断价值及其在术前分期中的作用。材料与方法：回顾性分析２７ 例经病理证实的喉咽癌的ＣＴ 表现，根据ＣＴ 征象对肿瘤进行分期并与手术病理结果对照分析。结果：肿瘤呈块状或椭圆形软组织肿块，形态不规则，等或混杂密度，增强扫描轻度增强；患侧杓椎和环椎间距＞ １０ ｍ ｍ 者分别占６７ ％ 和３０ ％ ，患侧甲杓间隙和环甲关节间距增宽的发生率为６３ ％ 及３０ ％ ；本组ＣＴ 术前肿瘤（ Ｔ） 分期和诊断颈部淋巴结转移的准确性为８５ ％ 和９０ ％ 。结论：ＣＴ 能很好地显示喉咽癌的大小、部位和侵犯范围及有无颈部淋巴结转移，有利于肿瘤的诊断和分期。
Objective: To investigate the value of CT in the diagnosis of hypopharyngeal carcinoma and its role in preoperative staging. Materials and Methods: The CT findings of 27 cases of pathologically confirmed hypopharyngeal carcinoma were retrospectively analyzed. The tumors were staging according to CT signs and compared with the results of surgical pathology. RESULTS: Tumors showed massive or oval soft tissue masses with irregular morphology, equal or mixed density, and slight enhanced contrast-enhanced scanning; 67% and 30% of the patients had ipsilateral iliac vertebrae and vertebral vertebral spacing> 10 m m, respectively. The incidence of widening of the gap between the affected side and the ring joints was 63% and 30%. The accuracy of preoperative CT (T) staging and cervical lymph node metastasis was 85% and 90%. Conclusion: CT can well show the size, location and extent of invasion of the hypopharyngeal carcinoma and whether there is lymph node metastasis in the neck, which is helpful for the diagnosis and staging of the tumor.
