目的探讨螺旋CT对胃肠道间质瘤的诊断价值。方法回顾性分析经手术病理证实的25例胃肠道间质瘤螺旋CT的特点。结果良性9例,恶性16例。胃部18例,食管1例,空肠4例,回肠2例,均为单发病灶。CT表现:(1)平扫,表现为圆或类圆形肿块影,9例良性肿块,8例边界清晰,16例恶性中11例边界不清,7例边缘呈分叶状,2例可见小钙化。(2)增强,25例肿瘤实质可见强化,以动脉期强化明显,但静脉期强化范围较动脉期广,其中15例肿块边缘模糊。结论螺旋CT是检查胃肠道间质瘤的一种重要手段,平扫结合增强检查有利于良恶性的判断,并对临床治疗及预后有着重要的指导价值。
Objective To investigate the diagnostic value of spiral CT in gastrointestinal stromal tumors. Methods The characteristics of spiral CT in 25 cases of gastrointestinal stromal tumors confirmed by surgery and pathology were retrospectively analyzed. The results were benign in 9 cases and malignant in 16 cases. 18 cases of stomach, esophagus in 1 case, 4 cases of jejunum, 2 cases of ileum, all single lesions. CT manifestations: (1) plain scan showed round or round mass, 9 cases of benign mass, clear border in 8 cases, 16 cases of malignant borderline in 11 cases were unclear, the edge of 7 cases was lobulated, 2 cases can be seen Small calcification. (2) enhanced, 25 cases of tumor parenchymal enhancement visible to the arterial phase was significantly enhanced, but the venous phase of the enhanced range of more than the arterial phase, including 15 cases of tumor edge fuzzy. Conclusion Spiral CT is an important method to detect gastrointestinal stromal tumors. The combination of plain scan and enhanced examination is good for the diagnosis of benign and malignant diseases, and has important guiding value for clinical treatment and prognosis.
