目的:回顾分析壶腹癌的CT表现,提高其诊断正确性.材料和方法:收集经CT检查后手术病理证实壶腹癌15例.全部病例均经GE9800或Elscint2400高分辨CT机行增强扫描,层厚、层距为5.0mm.结果:15例壶腹癌CT表现为1)胰头钩突肿块7例;2)十二指肠腔内充盈缺损8例;3)15例胆总管显著扩张合并下端截断性阻塞,同时合并肝内胆管、胆囊扩张11例;4)胰管扩张9例.根据壶腹癌占据部位在CT上提出分型:l)胰头钩突肿块型;2)十二脂肠乳头型;3)混合型.结论:改进CT检查技术,对早期诊断及提高壶腹癌诊断正确率有益.
Objective: To retrospectively analyze the CT findings of ampullary carcinoma and improve its diagnostic accuracy. Materials and methods: 15 cases of ampullary carcinoma confirmed by pathology after CT examination. All cases were enhanced by GE9800 or Elscint2400 high-resolution CT machines. Thickness and layer spacing were 5.0 mm. Results: CT findings of 15 cases of ampullary carcinoma were as follows: 1) 7 cases of pancreatic head hook tumor; 2) duodenal cavity filling defect; 8 cases; 3) 15 cases of significant expansion of common bile duct Combined lower truncated obstruction, combined with intrahepatic bile duct, gallbladder expansion in 11 cases; 4) pancreatic duct dilatation in 9 cases. Based on ampullary cancer occupies part of the proposed type on the CT: l) pancreatic head hook tumor mass type; 2) ten Digestive papillary type; 3) Mixed type. Conclusion: Improved CT examination technique is useful for early diagnosis and improvement of the diagnostic accuracy of ampullary carcinoma.
