A 72-year-old woman visited our hospital for a routine health examination and underwent abdominal ultrasonography, which revealed an intra-abdominal tumor. Abdominal computed tomography and magnetic resonance imaging showed a well-defined solid mass of ~3 cm in diameter lying adjacent to the stomach. The mass was preoperatively diagnosed as gastrointestinal stromal tumor of the stomach. At laparotomy, a well-encapsulated tumor was found in the lesser omentum. It was slightly adherent to the stomach wall but was removed without difficulty. Therefore, only enucleation of the tumor was performed. The excised tumor, which was 35 × 30 × 25 mm in size, had a white cut surface without necrosis or hemorrhage. According to the pathological findings, the tumor was classified as a very low-risk gastrointestinal stromal tumor originating in the lesser omentum. Gastrointestinal stromal tumor of the lesser omentum is very rare, and surgical resection is the only effective treatment modality.
一名72岁女性因常规健康检查前来我院就诊，并接受了腹部超声检查，结果显示腹内有肿瘤。腹部计算机断层扫描和磁共振成像显示，胃旁有一个直径约3厘米、边界清晰的实性肿块。该肿块术前被诊断为胃胃肠道间质瘤。剖腹手术时，在小网膜内发现一个包膜完整的肿瘤。它与胃壁有轻微粘连，但很容易被切除。因此，仅对肿瘤进行了剜除术。切除的肿瘤大小为35×30×25毫米，切面呈白色，无坏死或出血。根据病理结果，该肿瘤被分类为起源于小网膜的极低风险胃肠道间质瘤。小网膜胃肠道间质瘤非常罕见，手术切除是唯一有效的治疗方式。
