摘要 目的分析胃肠道间质瘤的CT表现特征,探讨CT对该肿瘤的诊断价值。方法回顾性分析经手术及病理证实的17例胃肠道间质瘤患者的CT影像学资料,并将大体病理所见与CT表现相对照。结果17例中食管间质瘤1例,胃间质瘤10例,十二指肠间质瘤2例,空肠间质瘤1例,回肠间质瘤1例,腹腔内肠道外间质瘤2例。17例中恶性者12例,良性者4例,不能确定良恶性者1例。17例肿瘤CT表现为外生性或内生性肿块,体积多较大,肿块最大径范围3~17.3cm,<5cm者4例,≥5cm者13例。肿块密度不均匀,呈囊实性,实性部分轻到中度强化,瘤内点状钙化灶2例,8例高度恶性肿物表现边缘强化,中心大片低密度。病理所见:肿瘤实性部分为由梭形细胞和(或)上皮样细胞组成,变性、出血、囊变及坏死在CT均表现为低密度。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定位,以及观察肿瘤与周围组织结构的关系。
