原发性小肠肿瘤的超声诊断探讨

Ultrasonographic diagnosis of primary small-intestinal tumors

目的 探讨超声检查对原发性小肠肿瘤的诊断价值。方法 对超声诊断的 2 2例原发性小肠肿瘤的临床资料进行回顾性分析 ,并与手术、病理检查对照。结果 超声图像改变可分为“假肾征”型、混合型和实性型 ,其中“假肾征”型仍是其特征性表现 ,同时可发现肠梗阻、胆道梗阻和转移征象。超声诊断符合率为 6 3.6 % (14 / 2 2 )。结论 超声诊断原发性小肠肿瘤是一种有价值的方法。

Objective To explore the ultrasonographic value in diagnosis of primary small intestinal tumor.Methods Twenty two cases of primary small intestinal tumors were diagnosed by ultrasonographic examination and confirmed by operation and pathology.Results The imagings of ultrasonography were divided into three types: 'pseudorenal' sign, compound and solid. 'pseudorenal' sign was the characteristic sonographic feature of the small intestinal tumor. Indirect signs including intestinal obstruction, dilatation of biliary duct and metastasis were found. The coincidence rate of diagnosis with ultrasonography was 63.6 %.Conclusions Ultrasonic diagnosis of primary small intestinal tumor is a valuable method.
