Gastrointestinal stromal tumors (GISTs), the most common sarcoma of the gastrointestinal tract, are mesenchymal tumors that generally arise in adults with a peak incidence in the sixth decade of life. Though most frequently found in the stomach or small intestine, GISTs may develop anywhere along the gastrointestinal tract. Approximately 1 in 4 GISTs are diagnosed incidentally, with imaging playing a crucial role in their detection and characterization. Due to their often clinically insidious growth, up to 25% of patients may already have metastatic disease at the time of diagnosis. In this article, we report the case of a 67-year-old woman who was incidentally diagnosed with a duodenal GIST. We analyze the computed tomography imaging findings and correlate them with the patient's clinical features.
胃肠道间质瘤（GISTs）是胃肠道最常见的肉瘤，是一种间叶组织肿瘤，通常发生于成年人，发病高峰在60岁左右。虽然GISTs最常出现在胃或小肠，但也可能在胃肠道的任何部位发生。约四分之一的GISTs是偶然诊断出来的，影像学在其检测和特征描述中起着关键作用。由于其生长往往在临床上较为隐匿，高达25%的患者在诊断时可能已经发生转移。在本文中，我们报告了一例67岁女性偶然诊断为十二指肠GIST的病例。我们分析了计算机断层扫描成像结果，并将其与患者的临床特征相关联。
