胃肠道间质瘤的64排螺旋CT影像特征与病理

Imaging Characteristics of 64-Detector Spiral CT and Pathology in Gastrointestinal Stromal Tumors

探讨胃肠道间质瘤64排螺旋CT的影像特征与病理。回顾性分析经手术病理和免疫组化证实的20例胃肠道间质瘤CT平扫和增强的影像征象。结果 20例胃肠道间质瘤患者中,胃间质瘤15例,小肠间质瘤2例,结肠间质瘤1例,直肠间质瘤1例,食道间质瘤1例;20例病理结果当中,良性间质瘤5例,交界性间质瘤8例,恶性间质瘤7例。结论:根据肿瘤的生长方向、形态、大小、CT增强特征、瘤周侵犯及转移等影像学特征,64排螺旋CT对胃肠道间质瘤的定性诊断有重要的作用。

To discuss the imaging features of 64 slice spiral CT and pathology in gastrointestinal stromal tumors. CT plain and enhanced findings of 20 cases of gastrointestinal stromal tumors confirmed by pathology and immunohistochemistry were retrospectively analyzed. Result： Among the 20 patients of gastrointestinal stromal tumors（ GIST）,15 cases were suffered from stomach,2 cases from small intestine,1 case from colon,1 case from colon and 1 case from esophagus; Among the 20 cases of gastrointestinal stromal tumors confirmed from pathology,there were 5 benign tumors,8 borderline tumors and 7 malignant tumors. Conclusion： Acording to imaging features of the growth direction,shape,size,CT enhanced characteristics,invasion around the tumor and metastasis,64-detector spiral CT is of great value of qualitative diagnosis of gastrointestinal stromal tumors.
