小肠恶性淋巴瘤的影像诊断(附18例分析)

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，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

Imaging Diagnosis of Intestinal Lymphoma--An Analysis of 18 Cases

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.
