摘要
目的探讨肾细胞癌的多层螺旋CT影像特点及其诊断价值。方法对30例术后病理证实的肾细胞癌,术前行多层螺旋CT平扫、增强扫描。结果在30例研究对象中,其中10例患者边界相对比较清晰;20例位于肾实质外围可凸出肾轮廓之外;低密度为液化坏死者12例,呈均匀等密度者为7例,呈较高密度或者较低密度者为5例;存在出血、钙化等高混杂密度影者为6例,病灶表现为囊性者3例,肾周脂肪间隙受侵模糊者10例。增强后实质部分强化,液化坏死区无强化。对减薄后的图像进行多平面重组、最大密度投影,显示下腔静脉及肾静脉内充盈缺损及动静脉瘘。术后病理为肾透明细胞癌24例,乳头状肾细胞癌6例。结论肾细胞癌CT表现有一定的特征性,多层螺旋CT对肾细胞癌影像特征的显示及诊断准确性高。
Objective To evaluate MSCT features and their value in diagnosis of renal renal cell carcinoma.Methods 30 cases with renal cell carcinoma confirmed by surgery and pathology were analyzed, all of whom were subjected to unenhanced and enhanced MSCT.Results Of the 30 cases in this study, 10 patients were sharpness of border, 20 cases were protruded of the kidney contours, 12 patients were with low density and liquefied necrosis, 7 with medium density, 5 cases were with high density or low density, 6 patients were hemorrhage and calcification, 3 cases were with cystic lesions, 10 patients were unclear of kidney fat.Solid lesion was strengthened at different degree in walland solid part and no enhancement in cystwall.All of them were dispose of the maximum intensityprojection and multipleplanar reconstruction, marked filling defect found in inferior vena cava and arteriovenous fistula.In cortical phase, clear cell RCC(24/30) and papillary RCC tended to be marked enhancement.Conclusion MSCT scan was a reliable technique in the dectection of renal cell carcinoma by imaging characteristics.
