摘要
目的分析CT对下咽癌的诊断价值。方法回顾分析经手术或局部活检病理证实的36例下咽癌的CT图像。结果梨状窝癌26例(72.2%),主要表现为梨状窝前壁、侧壁或后壁明显增厚,杓会厌皱襞增厚,梨状隐窝狭窄或消失,周围脂肪间隙消失。咽后壁癌或环后区癌7例(19.5%),主要表现为咽后软组织增厚,杓椎距或环椎距明显增宽。混合型癌3例(8.3%),主要表现为下咽区广泛的软组织增厚,咽腔变窄。结论CT可较准确地显示下咽癌形态、周围结构的侵犯,明确受侵器官和淋巴结转移情况,为临床手术提供指导。
Objective To assess the diagnostic value of CT for hypopharyngeal carcinoma. Methods CT findings in 36 patients with hypopharyngeal carcinoma confirmed pathologically were retrospectively analyzed. Results Pyriform sinus carcinoma was identified in 26 cases （72.20%）, the main manifestations were obvious thickening of aryepiglottic fold and the anterior,lateral and posterior walls of pyriform sinus,narrowing or disappearing of pyriform sinus and surrounding fat; carcinoma at retropharynx or postcricoid area, seven cases （19.5 %）, the main manifestations were thickening of retropharyngeal soft tissue and widening of the distance between cricoid caitilage and vertebra or between arytenoid and vertebra; mixed type carcinoma, three cases （8.3%）, the main manifestations were widespread thickening of soft tissue in hypopharyngeal area, narrowing of cavitas pharyngis. Conclusion CT can accurately show the shape of the tumor,adjacent structure and organs affected as well as lymph node metastases.
