目的:探讨肾母细胞瘤的超声和CT影像表现及诊断价值。方法:回顾性分析14例肾母细胞瘤的超声和CT表现,并与手术病理结果对照。结果:本组14例B超显示均为单侧病灶,瘤体形态呈圆形或类圆形,边界清楚,病灶呈实性者11例,囊实性者2例,囊性者1例,其中5例病灶内可见斑点状钙化,1例边缘呈环形钙化。CT平扫呈混杂密度,强化后瘤体呈不均匀强化;彩色多普勒血流显像(CDFI)均见数量不等的血流信号显示。结论:肾母细胞瘤的超声和CT影像表现具有一定的特征性,两者联合应用具有更高临床价值。
Objective: To investigate the manifestations and diagnostic value of nephroblastoma by ultrasound and CT imaging. Methods: The ultrasound and CT findings of 14 cases of nephroblastoma were retrospectively analyzed. The results were compared with the pathological findings. Results: All the 14 cases of B-ultrasound showed unilateral lesions. The shape of the tumor was round or round, with clear boundary, 11 cases with solid lesions, 2 cases with cystic solid, 1 case with cystic degeneration, Among them, 5 cases showed speckled calcification in the lesion, and 1 case had a peripheral calcification. CT scan showed a mixed density, enhancement of the tumor was uneven enhancement; color Doppler flow imaging (CDFI) were seen in varying amounts of blood flow signal display. Conclusion: The results of sonography and CT imaging of Wilms’ tumor have certain characteristics. The combined application of them has higher clinical value.
