摘要
目的 探讨小肠恶性淋巴瘤的CT和X线诊断及鉴别诊断。材料与方法 18例全部作消化道钡餐造影 ,其中 12例进行CT扫描检查。 18例均经手术、病理证实。结果 CT见肠壁增厚 12例 ,肠腔扩张与狭窄 8例 ,其中 4例单纯狭窄 ,溃疡 2例 ,腹腔、肝门、脾门淋巴结肿大 3例。消化道造影见肠管扩张与狭窄交替 16例 ,溃疡 10例 ,瘘道 3例。结论 消化道钡餐造影对小肠恶性淋巴瘤有良好的显示 ,还可以发现CT所不能显示的粘膜面 ,对于估计病变的范围 ,发现溃疡、窦道方面优于CT。但CT能清楚观察肠壁的厚度 ,以及肠道外有无淋巴结肿大 ,对于诊断和鉴别诊断 ,确定原发性淋巴瘤或继发性淋巴瘤以及肿瘤的分期能提供更多的信息。
Objective To discuss the diagnosis and the differential diagnosis of intestinal lymphoma.Materials and Methods Barium meal examination was performed in 18 cases with surgicallyand pathologicallyproved lymphoma, and 12 cases of them underwent additional CT scan.Results CT findings were as follows: thickened intestinal wall (n=12), intestinal dilatation or narrowing (n=8), ulcers (n=2), lymphadenectasis of abdominal cavity, porta hepatis and hilus of spleen (n=3). On barium meal exam, intestinal dilatation and narrowing (n=16), ulcers (n=10) and fistulae (n=3) were seen.Conclusion Barium meal exam can well demonstrate intestinal lymphomas, and display mucosal surface which cannot be revealed on CT scan. It is superior to CT scan in finding ulcers and fistulas, and in estimating the extent of the lesion. CT can show the thickness of the intestinal wall, demonstrate lyphadenopathy outside the intestinal loop, provide more useful information for diagnosing and staging of the tumor.
