摘　　要：目的探讨胃肠道间质瘤（GIST）的影像学表现、病理学特点及诊断方法。方法回顾性分析14例经手术及病理证实的GIST患者临床、病理及影像学资料。结果14例GIST均为单发，位于胃10例，小肠4例。肿瘤多为圆形、类圆形，少数为分叶状不规则形。免疫组化检查：CD117（＋）12例，CD34（＋）9例。结论影像学检查对GIST的诊断及定位有重要价值，但最后确诊有赖于病理组织学检查。Objective To evaluate the imaging features,pathologic characteristics and diagnostic methods of gastrointestinal stromal tumor（GIST）. Methods A retrospective study was performed to analyze the clinical pathological and imaging data of 14 GIST patients diagnosed by surgery and pathology. Results 14 cases of GIST were all solitary. 10 eases were located in stomach and 4 cases in small intestine. Tumors were mostly round or oval,and a few of them were irregular lobulated. Immunohistochemistry analysis： 12 cases were CDll7 positive and 9 cases were CD34 positive. Conclusion The imaging examination was important to the diagnosis and localization of GIST,but the final diagnosis of GIST depended on histopathological and immnnohistochemical examination.
