Gastrointestinal stromal tumors (GIST) comprised 0,2% of all GI tumors. They are typically asymptomatic, but can manifest with nonspecific GI symptoms, GI bleeding, or intussusception. The authors report a case of a 55-year-old female patient with hematochezia and a palpable mass on the left lower quadrant. Ultrasound revealed possible intussusception. However, CT scan did not show any signs of lesions or intussusception. On reevaluation, the mass was no longer palpable. The patient had recurrent episodes of hematochezia with need of transfusional support. CT enterography revealed a 20-24 mm jejunoileal lesion. A laparotomy was undertaken with small bowel resection containing the lesion. Histological examination confirmed GIST. GIST presentation as transient intussusception and intermittent GI bleeding is rare. This case report emphasizes the rarity of jejunoileal GIST, its clinical details, diagnostic study, and treatment.
胃肠道间质瘤（GIST）占所有胃肠道肿瘤的0.2%。它们通常无症状，但可表现为非特异性胃肠道症状、胃肠道出血或肠套叠。作者报告了一例55岁女性患者，有便血且左下腹可触及肿块。超声检查显示可能存在肠套叠。然而，CT扫描未显示任何病变或肠套叠迹象。再次评估时，肿块已无法触及。患者反复出现便血，需要输血支持。CT小肠造影显示空肠回肠有一个20 - 24毫米的病变。进行了剖腹手术，切除包含病变的小肠。组织学检查确诊为GIST。GIST表现为短暂性肠套叠和间歇性胃肠道出血较为罕见。本病例报告强调了空肠回肠GIST的罕见性、其临床细节、诊断研究及治疗方法。
