目的 :提高对累及胸廓入口区的食管癌的X线和CT表现的认识 ,并评价X线和CT对其诊断价值。材料和方法 :分析23例经手术和/或病理证实的胸廓入口区食管癌的X线和CT表现。结果 :X线可观察食管粘膜的改变、食管壁舒缩和钡剂通过的快慢 ,并能对食管癌进行分型。而CT能观察 :①食管壁增厚的程度 ;②食管周围脂肪间隙的改变 ;③邻近脏器和淋巴结受累情况。结论 :钡剂食管造影仍是发现、诊断和随访该区食管癌的首选和主要的检查方法 ,CT能进一步清楚地显示癌瘤外侵程度、受累的脏器以及提示有无周围淋巴结受累。
OBJECTIVE: To improve the understanding of X-ray and CT findings of esophageal cancer involving the thorax entrance area and to evaluate the diagnostic value of X-ray and CT. Materials and Methods: X-ray and CT findings of 23 cases of esophageal cancer at the thoracic portal area confirmed by surgery and / or pathology were analyzed. Results: X ray can observe esophageal mucosal changes, esophageal wall contraction and barium through the speed, and can type of esophageal cancer. The CT can observe: ① the extent of esophageal wall thickening; ② esophageal fat gap around the change; ③ adjacent organs and lymph node involvement. Conclusions: Barium esophageal angiography is still the first choice and the main method of detection, diagnosis and follow-up of esophageal cancer in this area. CT can further clearly show the degree of invasion, the organs involved and the presence of peripheral lymph nodes.
