An extragastrointestinal stromal tumor (EGIST) refers to the gastrointestinal stromal tumor in any location outside the gastrointestinal tract originates from mesenchymal tumors. The majority of the EGIST appeared as isolated mass, and multiple primary EGIST is quite rare. Here, we report a 36-year-old man of multiple EGIST in the abdominopelvic cavity, which was misdiagnosed as lymphoma on fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) imaging. The patient received adjuvant drug treatment (imatinib, 400mg/day) for three months, and then further resection of all lesions was performed. No recurrence was found in CT follow-up one year after the operation.
一个胃肠道外间质瘤（EGIST）是指任何位于胃肠道以外的胃肠道间质瘤起源于间叶组织肿瘤。大多数 EGIST 表现为孤立性肿块，而多发性原发性 EGIST 非常罕见。在这里，我们报告了一名 36 岁男性患有腹盆腔多发性 EGIST，在氟-18-氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）成像上误诊为淋巴瘤。患者接受了辅助药物治疗（伊马替尼，400mg/天）三个月，然后进一步切除了所有病变。术后一年 CT 随访未见复发。
