摘要 目的:探讨胃肠道间质瘤的CT表现特征。方法:回顾性分析经手术及病理证实的11例胃肠道间质瘤患者的CT影像资料,并将大体病理所见与CT表现相对照。结果:肿瘤位于胃部2例,十二指肠2例,空肠3例,回肠2例,直肠1例,肠系膜内1例。发生于小肠的7例中4例有便血史或便潜血阳性。11例中恶性肿瘤8例,交界性2例,良性1例。11例中10例肿块CT表现为外生性肿块,多较大,其中恶性肿块直径4~16cm,直径<5cm者1例,≥5cm者7例。肿物密度不均匀,呈囊实性,实性部分中度至明显强化,肿块内伴有溃疡形成1例。结论:胃肠道间质瘤的CT表现具有一定特点,CT检查有助于胃肠道间质瘤的定位,以及观察肿瘤与周围组织结构关系情况。
