We report an unusual case of a pedunculated gastrointestinal stromal tumor (GIST) of the stomach with extragastric growth. An 84-year-old woman was referred to our hospital for investigation of anemia. Barium meal examination showed a defect occupying the lesser curvature of the stomach from the middle of the corpus to the fornix and an abdominal computed tomography scan, showed a lesion, 20 cm in diameter, touching the surface of the spleen. Laparotomy revealed a tumor located between the liver and spleen. As the tumor appeared to be connected with the posterior wall of the gastric corpus by a pedicle, it was resected with a pedunculated lesion of the stomach. Based on the pathological findings, the tumor was diagnosed as a GIST of uncommitted type, with low-grade malignancy.
我们报告一例罕见的带蒂胃胃肠道间质瘤（GIST）并向胃外生长的病例。一名84岁女性因贫血问题转诊至我院。钡餐检查显示胃体中部至胃穹窿小弯侧有充盈缺损，腹部计算机断层扫描显示一个直径20厘米的病灶，与脾脏表面相连。剖腹手术发现肿瘤位于肝脏和脾脏之间。由于肿瘤似乎通过蒂与胃体后壁相连，遂将其连同胃的带蒂病变一并切除。根据病理检查结果，该肿瘤被诊断为未定型GIST，低度恶性。
