目的探讨胃肠道间质瘤的CT表现及诊断价值。方法回顾性分析17例经手术病理和免疫组化证实的胃肠间质瘤,均行CT平扫和动态增强扫描。结果肿瘤位于胃部10例,空肠4例,回肠2例,结肠1例,CT扫描表现为:肿块向腔外或腔内生长,较大肿块内可见囊变坏死区,增强扫描肿块均匀等密度者呈均匀明显强化,坏死囊变区无强化。结论 CT对胃肠道间质瘤的诊断价值较大,但其CT表现缺乏特异性,与平滑肌肿瘤及神经源性肿瘤鉴别有一定限度,确诊有赖于病理学检查。
Objective To investigate the CT findings and diagnostic value of gastrointestinal stromal tumors. Methods Retrospective analysis of 17 cases of gastrointestinal stromal tumors confirmed by surgery and pathology and immunohistochemistry were performed CT scan and dynamic contrast-enhanced scan. Results The tumor was located in the stomach in 10 cases, jejunum in 4 cases, ileum in 2 cases and colon in 1 case. The CT scan showed that the tumor grew into the cavity or inside the cavity. The larger necrosis area could be seen in the larger tumor and the even density Significantly enhanced were uniform, necrotic cystic area without strengthening. Conclusion CT is of great value in the diagnosis of gastrointestinal stromal tumors. However, its CT features are not specific. There are some limitations in the differential diagnosis between CT and neurogenic tumors. CT diagnosis depends on pathological examination.
