摘要
目的:探讨多层螺旋CT对胃肠道间质瘤的诊断价值。方法:回顾性分析10例经手术及病理证实的胃肠道间质瘤的CT表现特点。结果:肿瘤位于胃部5例,十二指肠2例,空肠2例,回肠1例。肿块直径<5.0cm者3例,直径≥5.0cm者7例。呈类圆形2例,呈多分叶状8例。术后病理证实为良性4例,低度恶性6例。结论:胃肠道间质瘤的表现有一定特点,有助于胃肠道间质瘤的定位,并可初步鉴别肿瘤的良恶性,但确诊需依靠免疫组化和电子显微镜检查。
Objective： To investigate the specific CT findings of gastrointestinal stromal tumors （GIST） by Multi-slice Helical CT （MSCT） .Methods：A retrospective analysis of 10 eases of GIST confirmed by surgery, and pathology were performed. The appearance of GIST was evaluated by MSCT.Results：There were 5 eases of GIST in the stomach, 2 cases in the duodenum, 2 cases in the jejunum and 1 case in the ileum and bladder-bowel fossae respectively. There were 3 patients with tumor diameter smaller than 5.0cm and 7 patients with the diameter equal or larger than 5.0cm. The shapes were round or oval in 2 cases and lobulated in 8 cases. The density was uniform in 3 cases and not uniform in 7 cases. There were 4 benign neoplasms and 6 low-grade malignant neoplasms confirmed by post-operative pathology.Conclusion：The imaging characteristics of GIST from MSCT can contribute to the positioning of GIST and preliminary identification of benign and malignant tumors. The clear diagnosis relies on the immunohistochemistry and electron microscopy.
