小肠原发性肿瘤的影像学诊断

Imaging diagnosis of small intestinal tumor

目的:探讨小肠原发性肿瘤的CT和消化道造影诊断及鉴别诊断。资料与方法:40例全部作消化道钡餐造影,其中28例进行CT扫描检查。所有病例均经手术、病理证实。结果:消化道造影见肠腔狭窄20例,充盈缺损19例,肠梗阻13例,管壁僵硬、粘膜破坏及环状皱襞消失主要见于恶性肿瘤。CT扫描发现腹内肿物28例。结论:消化道钡餐造影对小肠原发性肿瘤有良好的显示,还可以发现CT所不能显示的粘膜面,仍是小肠原发性肿瘤简便的首选检查方法,CT为重要的补充检查,恰当地结合应用可以提高小肠原发性肿瘤的诊断准确率。

Objective: To discuss the diagnosis and the differential diagnosis of primary small intestinal tumor. Materials and Methods: Barium meal examination was performed in 40 cases and proved by surgery and pathology, 28 cases of them underwent additional CT scanning. Result: Barium meal examination findings were as follows: intestinal dilatation(n=20), intraluminal filling defects(n=19), intestinal obstruction(n=13), stiffened intestinal wall and displaced mucosal folds(n=22) were seen in intestinal malignancy. On CT scans soft tissue mass was found in 28 cases. Conclusion: Barium meal examination is the first choice in the diagnosis of small intestinal tumor. It can demonstrate intestinal tumor well, and display mucosal surface which can not be revealed on CT scan. CT is an important supplement. Combination of barium meal examination and CT scan can improve the clinical diagnosis of small intestinal tumor.
