Abstract

Various pathologies could lead to occult gastrointestinal (GI) bleeding. Here we report the case of a 73-year-old woman who presented with hematochezia and syncope, and was found to have a large bleeding GI stromal tumor incidentally from 99m Tc-RBC scintigraphy. This study was done after negative workup with CT angiography, colonoscopy, and capsule endoscopy for the source of GI bleeding. Final pathology confirmed the mass being a low-grade GI stromal tumor after exploratory laparotomy.

摘要

各种病理学变化都可能导致隐匿性胃肠道（GI）出血。在这里，我们报告了一例 73 岁女性患者，其因血便和晕厥就诊，99mTc-RBC 闪烁显像意外发现了一个大的出血性胃肠道间质瘤。在对胃肠道出血的来源进行 CT 血管造影、结肠镜检查和胶囊内镜检查后，该检查无异常。剖腹探查后，最终的病理证实肿块为低度胃肠道间质瘤。
