摘要
目的:分析胃肠道间质瘤的CT征像,以提高其诊断及鉴别诊断水平。方法:回顾性分析经手术和病理证实的13例胃肠道间质瘤患者的CT影像及临床资料,并将大体病理所见与CT表现对照。结果:肿瘤位于胃部3例,十二指肠2例,空肠4例,回肠2例,肠系膜内2例。13例中恶性9例,潜在恶性2例,不能确定良恶性2例。13例中12例肿块表现为外生性肿块,多较大,其中恶性肿块最大径3～26cm。肿瘤密度不均匀,呈囊实性,实性部分中度强化至明显强化,肿瘤边缘分叶2例。结论:CT对于胃肠道间质瘤的定位和提示诊断都具有非常高的价值,但对肿瘤良恶性的判断有一定限度,确诊有赖于病理学检查。
Objective：To analyze the CT features of gastrointestinal stromal tumors, and to enhance its diagnosis and differential diagnosis levels. Methods：The imaging and clinical data for 13 patients with gastrointestinal stromal tumors were analyzed retrospectively, who were diagnosed by operation and pathology. Results：There were 3 in stomach, 2 in duodenum, 4 in jejunum, 2 in ileum, and 2 in mesenterium. Among these 13 patients, 9 belong to malignant, 2 belong to potential malignant, and 2 patients could not be determined for malignant or benign tumor. There were 12 patients with large exodemic masses, and the largest diameters for malignant tumor were measured from 3 to 26 cm. The density for these tumors was uneven, and most of them were cystic and solid. The solid was intensified, and its verge divided into two parts. Conclusion：The CT is effective in orientation and diagnosis of gastrointestinal stromal tumors, but it maybe limited in differentiating of malignant and benign tumor, which should be given final diagnosis by pathological methods.
