摘要 目的:探讨小肠间质瘤的影像表现及诊断价值。方法:回顾性分析16例经手术病理证实的小肠间质瘤的胃肠道造影(GI)及CT检查。结果:16例均行胃肠道造影及CT检查,恶性14例,良性2例;肿瘤以向腔外生长为主(10例),类圆形或椭圆形居多(11例),绝大多数境界清楚(13例);良性瘤体平均大小3.1cm×4.4cm,平扫时密度均匀,增强后轻-中度均匀强化,CT值净平均增21Hu;恶性瘤体平均大小7.7cm×6.3cm,密度不均匀(11例),瘤中间坏死多见,增强后明显到显著强化,CT值平均净增加57Hu。3例恶性瘤体旁见成簌状或线状排列血管影,2例侵犯周围组织,1例肝脏转移。胃肠道造影主要表现为局部黏膜皱襞变平或消失,肠腔偏侧性狭窄,肿块黏膜面溃疡,病变段与正常肠壁分界清楚。结论:小肠间质瘤有一定的影像学检查特点,GI及CT检查能确定小肠间质瘤的存在,CT能估计病变的良、恶性,对治疗起指导性作用。
