目的:研究肿瘤侵犯食管入口时的影像学诊断价值。方法:回顾分析22例临床病理证实的侵犯食管入口的肿瘤的X线、CT和MRI表现。结果:22例常规X线检查均见钡剂通过食管入口受阻,19例见食管入口狭窄、黏膜破坏等,9例经CT或MRI检查发现食管环咽段增厚伴杓—椎间距和环—椎间距增大,7例MRI均发现肿块与食管入口的界限模糊、消失,5例CT发现杓状软骨破坏,4例甲状骨破坏。结论:X线吞钡检查食管入口狭窄、黏膜破坏,CT或MRI发现食管环咽段增厚伴杓—椎间距或环—椎间距增大等是食管入口处原发或受侵肿瘤的影像学特征性表现。
Objective: To study the imaging diagnostic value of tumor invasion esophageal entrance. Methods: The X-ray, CT and MRI findings of 22 cases of clinically and pathologically confirmed esophageal invasion were retrospectively analyzed. Results: Twenty-two patients underwent routine X-ray examination of barium through the esophageal portal obstruction, 19 cases of esophageal stricture and mucosal destruction, and 9 cases of thoracic esophageal thickening with esophageal fossa-vertebral and intercostal space examination by CT or MRI Increased, 7 cases of MRI were found in the boundary between the tumor and esophageal obstruction, disappear, 5 cases of arytenoid articular cartilage destruction found in 4 cases of destructive thyroid bone. Conclusion: X-ray barium swallowed the esophageal stenosis and mucosal damage, CT or MRI found esophageal throat thickening with spongy - intervertebral space or inter-lumbar intervertebral spacing increased esophageal entrance is the imaging features of the tumor at the entrance or which performed.
