Gastrointestinal stromal tumors (GISTs) are neoplasms that arise from the wall of the gastrointestinal tract or, rarely, from other intra-abdominal tissues. They are the most common mesenchymal tumors of the gastrointestinal tract and they should be considered in the differential diagnosis of obscure gastrointestinal bleeding. Computed tomography angiogram (CTA) can be utilized as an alternative imaging study when endoscopic and colonoscopy results are non-diagnostic. We report a case of a 59-year-old woman who presented with recurrent episodes of obscure overt gastrointestinal bleeding secondary to a gastrointestinal stromal tumor (GIST).
胃肠道间质瘤（GISTs）是起源于胃肠道壁的肿瘤，很少起源于其他腹腔内组织。它们是胃肠道最常见的间叶性肿瘤，在不明原因的胃肠道出血的鉴别诊断中应予以考虑。当内镜检查和结肠镜检查结果无诊断价值时，计算机断层血管造影（CTA）可作为一种替代的影像学检查。我们报告一例59岁女性患者，因胃肠道间质瘤（GIST）出现反复不明原因的显性胃肠道出血。
