摘要
目的探讨胃肠道间质瘤(GIST)的病理学特点及CT表现。方法回顾性分析30例经手术及病理证实的GIST临床、病理及影像学资料。结果30例病例中肿瘤均为单发,位于胃15例,空肠5例,回肠6例,结肠2例,直肠1例,腹膜后1例。本组10例行CT检查的病例中,判断病灶起源部位与病理结果相符合者5例,2例误诊;CT判断间质瘤良恶性准确率为70%;CT表现肿瘤密度不均匀,对应于病理学中的出血、坏死及囊变。结论GIST的病理学改变与CT表现相一致,但最后确诊有赖于病理组织学和免疫组化检查.
Objective To evaluate the CT features of gastrointestinal stromal tumor(GIST)with pathology diagnosis. Methods The clinical and imaging findings of 30 patients with surgical and pathologically diagnosis of GISTs were retrospectively analyzed. 10 of 30 cases undarge CT scan. Results Of 30 patients, the tumors were located in gastic (n=15), jejunum (n=5), ileum (n=6), colon(2),rectum (1), post-peritoneum(l), respectively. Accuracy rates of CT diagnosis for localizing and differentiating the innocence or malignancy of GISTs were 50% (5/10)and 70%(7/10) respectively. Imaging findings were heterogeneous density or signal intensity, corresponding to hemorrhage, necrosis and cystic change. Gonclusion The CT features of GISTs accord with the pathological features, but the final diagnosis of GISTs depended on histopathological and immunohistochemical examination.
