目的探讨十二指肠间质瘤的CT表现及诊断价值。方法回顾性分析手术或病理证实的16例十二指肠间质瘤患者的CT平扫及增强扫描资料。结果 16例十二指肠间质瘤中降部9例,水平部5例,升部2例。良性间质瘤6例,均向腔内生长,呈圆形或类圆形,密度均匀,边界清楚。恶性间质瘤7例,向腔外生长6例、腔内外生长1例,肿瘤边缘有分叶,密度不均匀,明显不均匀强化6例,均匀强化1例,周围组织侵犯或远处转移5例。潜在恶性3例,均向腔内外生长,密度均匀。CT检查的敏感度为100%,定位准确率为93.8%,定性准确率为75%。结论 CT平扫及强化能准确显示十二指肠间质瘤的部位、形态、大小及其血供,对鉴别肿瘤良恶性有重要临床价值。
Objective To investigate the CT findings and diagnostic value of duodenal stromal tumors. Methods Retrospective analysis of 16 cases of duodenal stromal tumors confirmed by surgery or pathology CT scan and enhanced scan data. Results In the 16 cases of duodenal stromal tumors, there were 9 cases in descending part, 5 cases in horizontal part and 2 cases in ascending part. Six cases of benign stromal tumors, all to the cavity growth, was round or round, uniform density, clear boundary. Malignant stromal tumors in 7 cases, extraluminal growth in 6 cases, 1 case of growth in vitro and in vivo, lobes edge of tumor, uneven density, significantly enhanced in 6 cases, uniformly enhanced in 1 case, surrounding tissue invasion or distant metastasis 5 example. Potential malignant in 3 cases, both to the cavity growth, density and uniform. The sensitivity of CT examination was 100%, the accuracy of positioning was 93.8%, and the qualitative accuracy was 75%. Conclusion CT scan and enhancement can accurately show the location, shape, size and blood supply of duodenal stromal tumors, which has important clinical value in differentiating benign and malignant tumors.
