【摘要】 目的:探讨肠道恶性间质瘤的CT表现。资料和方法:回顾性分析7例肠道恶性间质瘤的CT征象,十二指肠2例,小肠4例,累及多节段肠管1例。结果:显示为起源于肠道的软组织肿块,边缘光整或不规则,平扫密度不均匀者5例,内部见不规则低密度灶,CT值23～42HU,均匀者2例。增强扫描5例肿块呈不均匀增强,CT值27～56HU。肿块内有钙化1例,肝转移2例。结论:肠道恶性间质瘤的CT表现具有一定特征,表现为起源于肠道的软组织肿块,可单发或多发,平扫密度多不均匀,增强后不均匀强化,可有钙化及远隔转移。更多还原

【Abstract】 Objective: To discuss the CT features of intestinal stromal tumors.Materials and Methods: The CT features of 7 cases of malignant intestinal stromal tumors were analyzed respectively,2 cases located at duodenum,4 cases at jejunum and ileum,1 case located at multisegments of intestine and colon.Result: All cases presented as soft tissue tumors arising from intestinal wall,with a clear or irregular margin,5 cases showed inhomogeneous density on plain scan,with low attenuation areas inside the tumor,the CT values were 23～42HU,5 cases showed inhomogeneous enhancement,CT values were 27～56HU.One case showed calcification,2 cases had liver metastasis.Conclusion: The CT of intestinal stromal tumors had some specific features: the tumor arising from intestine wall,single or multi focuses,on the plain scan the attenuation were inhomogeneous in most cases,while on contrast,inhomogeneous enhancement were obvious.The tumor may have calcification and remote metastasis.更多还原
