摘要
①目的探讨胃肠道间质瘤(GIST)的CT征象与特点。②方法回顾性分析26例经手术和免疫组织化学证实的GIST患者的临床资料及CT资料。26例GISP均行螺旋CT平扫和动态增强扫描。③结果26例GIST中,良性12例,恶性14例。肿瘤位于胃部10例,空回肠10例,直肠2例,小网膜4例;CT平扫病灶14例呈不规则形软组织肿块影,10例呈类圆形,2例呈葫芦状,增强扫描后病灶中度或明显强化,18例密度不均,8例密度较均匀。④结论GIST的CT表现均具有一定的特征性。
Objective To study the CT signs and features of gastrointestinal stromal tumors （GIST）. Material and methods ： The clinical data and CT images of 26 patients with GIST conformed by surgery and immunity tissue chemistry were retrospectively analyzed. Noncontrast CT scan and dynamic contrast - enhanced scan were performed in 26 GIST cases. Results Among 26 cases of GIST, benign and malignant tumor was 12 and 14 cases respectively;10 cases located in stomach, 10 cases in jejunum or ileum,2 cases in recta and 4 cases in lesser omentum. The noncontrast CT scan showed 14 cases with irregular soft tissue masses, 10 cases with round - like appearance, and 2 cases with bottle - gourd shape. The contrast - enhanced scan showed all tumors moderate or significant enhancement, 18 cases with inhomogeneous enhancement and 8 cases with homogeneous enhancement. Conclusion The CT signs of GIST were characteristic.
