目的探讨胃肠道间质瘤的CT表现及临床诊断价值。方法回顾性分析经手术病理证实的31例胃肠道间质瘤CT表现。结果本组中胃间质瘤7例,小肠间质瘤16例,结肠间质瘤2例,直肠间质瘤1例,难以确定部位者5例。31例中良性3例,交界性6例,恶性22例。肿瘤呈类圆形或不规则形,密度均匀实性者6例,不均匀实性者14例,囊实性混合者11例,有2例有钙化灶。增强扫描有3例均匀强化,3例不均匀强化,内有斑点状变性坏死灶;25例呈不均匀明显强化,肿块内可见不同程度的变性、坏死区。3例良性者为均匀类圆形实性肿块,直径<5cm。交界性与恶性者形态、大小、密度等无明显差别,肿瘤直径均>5cm。结论对胃肠道间质瘤CT检查有助于发现肿块,定位准确,帮助判断肿瘤的良恶性程度。
Objective To investigate the CT findings and clinical diagnostic value of gastrointestinal stromal tumors. Methods Retrospective analysis of 31 cases of gastrointestinal stromal tumors confirmed by surgery and pathology CT findings. Results The group of gastric stromal tumors in 7 cases, 16 cases of small intestinal stromal tumors, 2 cases of stromal tumors, 1 case of rectal stromal tumors, difficult to determine the site in 5 cases. Among the 31 cases, 3 were benign, 6 were borderline, and 22 were malignant. Tumors were round or irregular, with 6 cases of uniform density and density, 14 cases of non-uniform solidity, 11 cases of cystic solid mixed and 2 cases of calcification. Enhanced scanning of 3 cases of uniform enhancement, 3 cases of uneven enhancement, there are spot-like degeneration and necrosis; 25 cases showed uneven significantly enhanced mass showed varying degrees of degeneration and necrosis. 3 cases of benign were uniform round solid mass, diameter <5cm. Borderline and malignant shape, size, density, etc. no significant difference in tumor diameter> 5cm. Conclusion CT examination of gastrointestinal stromal tumors can help to find lumps, accurate positioning, to help determine the degree of benign and malignant tumors.
