原发性十二指肠腺癌的影像诊断分析

Imaging Features of Patients with Primary Duodenal Cancer

目的探讨原发性十二指肠腺癌影像学诊断的价值。方法回顾性分析,11例经手术证实的原发性十二指肠腺癌的数字胃肠低张气钡双重造影及CT平扫和增强的影像资料。结果双重造影表现为十二指肠局限性狭窄,不规则充盈缺损及龛影,黏膜破坏,近端肠管扩张;CT检查表现为十二指肠壁增厚,管腔狭窄伴软组织肿块,增强扫描显示肿块明显不均匀强化。结论数字胃肠低张气钡双重造影及CT平扫与增强检查,对原发性十二指肠腺癌的诊断与鉴别诊断有重要价值。

Objective To investigate the imaging features of patients with primary duodenal cancer. Methods Double contrast examination （DCE） and CT scan of 11 patients with pathologically-proved primary duodenal cancer were retrospectively analyzed. Results The main DCE findings included constriction of the duodenum,local irregular filling defect, niche shadow and local mucosa destroy. CT findings were thickened duodenal wall, local irregular constriction and soft tissue mass, with irregular contrast enhancement. Conclusion DCE and CT play an imortant role in the diagnosis of duodenal cancer.
