目的:探讨胃肠道间质性肿瘤的影像学诊断方法。方法 :对 5例胃肠道间质性肿瘤进行影像学诊断 ,3例行胃肠造影 ,1例行小肠造影 ,1例行 CT超声检查。结果:影像学检查发现胃贲门、胃体上部、胃底后壁、空肠、回肠间质瘤各 1例 ,均经手术病理证实为胃肠道间质性肿瘤。 2例免疫组化 S- 10 0 (+)、Vim(+)、Des(+)。 1例 CD34(+) ,PCNA(- ) ,p5 3(- )。结论:常规 X线检查对照内窥镜检查为发现诊断本病的主要手段 ,对胃肠道外侵犯的肿瘤选择应用 CT。
Objective: To investigate the imaging diagnosis of gastrointestinal interstitial tumors. Methods: Five cases of gastrointestinal interstitial tumors were diagnosed by imaging, three cases of gastrointestinal angiography, one case of small bowel angiography, and one case of CT ultrasound examination. Results: Imaging examination found gastric cardia, upper gastric body, gastric fundal wall, jejunum, ileum stromal tumor in 1 case, both confirmed by surgical pathology of gastrointestinal stromal tumors. Two cases of immunohistochemical S-10 0 (+), Vim (+), Des (+). One case of CD34 (+), PCNA (-), p5 3 (-). Conclusion: Conventional X-ray examination of control endoscopy for the diagnosis of the disease found in the main means of tumor selection of gastrointestinal invasion of CT.
