摘要 目的:分析胃肠道间质瘤(GIST)的CT表现特点,探讨CT对该肿瘤的诊断价值。材料与方法:回顾性分析我院经手术病理证实的胃肠道间质瘤23例,术前均行CT平扫和增强扫描。结果:肿瘤发生于胃16例,小肠6例,肠系膜1例,病灶多呈圆形或类圆形。生长方式以腔内生长者6例,腔外生长者10例,跨壁生长者6例;平扫:肿瘤呈均匀等密度者11例;肿瘤密度不均者12例。增强扫描:病灶明显强化者8例,不均匀强化者15例。23例胃肠道间质瘤中,良性10例,肿块多小于5cm,边界清楚,表现为均匀强化,恶性者13例,肿块直径大于5cm,边界多不清楚,3例肿块内有坏死,2例与肠腔相通,出现气-液平面。结论:GIST的CT表现具有一定的特征性。消化道来源的膨胀性生长的肿块,和/或伴有囊变、坏死或与消化道相通和增强后呈均匀或不均匀强化者,应考虑GIST可能,且CT对于胃肠道间质瘤的定位准确,对肿瘤良恶性的判断很有价值,确诊有赖于病理组织学及免疫组化检查。
