十二指肠恶性肿瘤的影像诊断

目的回顾性分析十二指肠恶性肿瘤的影像所见。方法原发肿瘤１３例，继发肿瘤３例，１６例病人均行上消化道气钡双重造影。５例病人行ＣＴ检查，２例行血管造影，２例壶腹部癌行Ｂ超检查，其中１例行ＥＲＣＰ检查。结果所有病人均经手术切除，将Ｘ线所见与病理结果对照分析，腺癌７例，平滑肌肉瘤６例，继发性癌３例。结论消化道造影是十二指肠病变的首选检查方法。本组病例均能提示病变部位，其中１３例定性诊断正确，但对一些外生性肿瘤，造影有其局限性，应结合ＣＴ、Ｂ超综合诊断。

Imaging Diagnosis of Duodenal Malignant Tumor

Objective We retrospectively analysed the view of duodenal malignant tumor based on the imageology. Mathods Thirteen cases of primary tumor, three cases of secondary tumor. All patients had been examined with upper alimentary tract gas-Ba contrast examination, five with CT scan, two with angiography, two with B ultrosound examination, including one with ERCP. Results All of sixteen malignant tumors was resected. Contrasted and analysed the view with imageology and pathology, there are seven adenocarcinomas, six leiomysarcomas and three secondary cancers. Conclusion Alimentary tract contrast examination is the first choice for duodenal diseases. To all of the sixteen patients, alimentary examination could reveal the location of the illness, thirteen of them with qualitative diagnosis correctly. However, contrast examination has some limitations for exogenous tumors. It should be combined with CT and B ultrosound for these cases.
