摘要 目的分析总结胃肠道外间质瘤(EGIST)的多层螺旋CT(MSCT)表现,以提高对其影像表现的认识。方法回顾性分析经组织病理证实的10例EGIST的MSCT表现特点。结果肿瘤位于网膜及肠系膜6例,腹膜后4例;不规则形或分叶状7例,类圆形3例;肿瘤长径>10 cm者8例;平扫肿物密度不均,10例均可见斑片样坏死,5例有明确囊性变,3例内部伴钙化。增强检查结果显示肿物呈不均匀强化,其中中度强化6例,明显强化4例;肿物内见血管影8例,仅周围见血管包绕2例;病变与邻近胃肠道间脂肪间隙欠清晰或不清晰者8例,其中相邻肠壁无强化者6例;肿物与胃肠道间可见血管弓2例。结论 EGIST的MSCT表现为大肿块,形态不规则,增强检查结果显示中度、明显强化、坏死、囊性变;肿物与周围结构分界相对清晰,邻近肠壁无异常强化;MSCT有助于EGIST的定位及定性诊断。
