【摘要】 目的分析胸段食管癌喉返神经链淋巴转移的多层螺旋CT(MSCT)影像表现及其诊断价值。方法以2014年1月—2016年6月拟行三野淋巴结清扫术的100例胸段食管癌患者为研究对象,术前均行MSCT平扫及增强扫描,观察其影像学表现,以病理结果为金标准,分析MSCT诊断喉返神经链淋巴结转移的敏感度、特异度与准确度。结果术中取出双侧喉返神经链淋巴结296枚,病理证实淋巴结转移45枚。MSCT对喉返神经链淋巴结转移诊断敏感度、特异度和准确度分别为82.22%、86.85%和86.15%。MSCT影像显示转移淋巴结短径为(0.50±0.13)cm,长径为(0.81±0.12)cm,长短径比均≤1.6,边缘模糊24枚,密度均匀38枚,淋巴结内增强扫描显示环形强化8枚。结论 MSCT对胸段食管癌喉返神经链淋巴结转移的诊断具有较大的临床价值。更多还原

【Abstract】 Objective To analyze the imaging features and diagnostic value of multi-slice spiral CT( MSCT) for thoracic esophageal carcinoma with lymph node metastasis in recurrent laryngeal nerve. Methods A total of 100 patients with thoracic esophageal carcinoma,who underwent three-field lymph node dissection during January 2014 and June2016,were recruited in the study. All patients underwent preoperative MSCT scan and enhanced scan,and the imaging findings were observed. The sensitivity,specificity and accuracy of MSCT in diagnosis of lymph node metastasis of recurrent laryngeal nerve were analyzed by pathological results as the golden standard. Results During operation,296 cases of bilateral recurrent laryngeal nerve lymph nodes were removed,and lymph node metastasis was confirmed in 45 cases by pathological results. The sensitivity,specificity and accuracy of MSCT in diagnosis of lymph node metastasis of recurrent laryngeal nerve were 82. 22%,86. 85% and 86. 15% respectively. MSCT images showed that the short diameter of lymph node metastases was( 0. 50 ± 0. 13) cm; the long diameter was( 0. 81 ± 0. 12) cm; the average ratio of long and short diameter was lower than 1. 6; there were 24 cases of fuzzy edges and 38 cases of homogeneous density; the intralymph node enhanced scan showed 8 cases of ring enhancement. Conclusion MSCT has clinical value in diagnosis of thoracic esophageal carcinoma with lymph node metastasis in recurrent laryngeal nerve.更多还原
