目的 :探讨超声对肠道肿瘤的诊断及鉴别诊断价值。方法 :回顾性分析 92例经内窥镜或手术、病理证实的肠道肿瘤疑诊患者的超声声像图特点。结果 :92例中 ,超声诊断肠道肿瘤 75例 ,特征表现为“靶环征”和“假肾征”,其中结肠肿瘤 5 6例 ,小肠肿瘤 5例 ,直肠肿瘤 14例 ;超声诊断肠结核 1例 ,克罗恩病 2例 ;超声误诊、漏诊或未能提供阳性诊断 14例。结论 :“靶环征”及“假肾征”并非肠道肿瘤所特有的超声表现 ,应与肠结核、克罗恩病等鉴别 ,以提高诊断准确性
Objective: To investigate the diagnosis and differential diagnosis of intestinal tumor by ultrasound. Methods: The echocardiographic features of 92 cases of suspected intestinal tumor confirmed by endoscopy or surgery were retrospectively analyzed. Results: In 92 cases, 75 cases of intestinal tumors were diagnosed by ultrasound. The features of the tumors were “target ring sign” and “fake kidney sign”. Among them, 56 were colon tumors, 5 were small intestinal tumors and 14 were rectal tumors. Ultrasonography was used to diagnose intestinal tuberculosis 1 case, Crohn’s disease in 2 cases; ultrasound misdiagnosis, missed diagnosis or failed to provide positive diagnosis in 14 cases. Conclusion: “Target ring sign” and “pseudo-kidney sign” are not characteristic of intestinal tumors and should be distinguished from intestinal tuberculosis and Crohn’s disease to improve diagnostic accuracy
