目的 :探讨CT对肾母细胞瘤的诊断价值 ,指导临床治疗。资料与方法 :回顾性分析 43例病理证实为肾母细胞瘤平扫加增强扫描的CT征象。结果 :肿瘤单侧多见 ,也可为双侧 ,多发生于肾脏一极 ,也可全部 ,常表现为强化不明显的实性肿块 ,瘤内常有坏死、囊变 ,少数有出血、钙化 ,典型表现为残存肾实质变薄 ,呈新月形、环形 ,或肾的正常结构消失。本组术前发现病灶 10 0 % ,诊断准确率 95 %。结论 :CT增强扫描能发现小病灶的肾母细胞瘤 ,很好地评价对侧肾脏的情况 ,并能明确肿瘤的范围以及转移的情况 ,对肿瘤的分期、指导临床制定治疗方案有重要的意义。
Objective: To investigate the diagnostic value of CT on nephroblastoma and to guide the clinical treatment. Materials and Methods: A retrospective analysis of 43 cases of pathologically confirmed nephroblastoma with enhanced CT scan. Results: Unilateral unilateral more common, but also for bilateral, occurred in the kidneys more than one pole, but also all, often showed no obvious solid mass enhancement, tumor often necrosis, cystic change, a small number of bleeding, calcification , The typical performance of remnant renal parenchyma thin, crescent-shaped, ring, or the disappearance of the normal structure of the kidney. The group found 100% lesions before surgery, the diagnostic accuracy of 95%. Conclusion: CT enhanced scan can detect small lesions of the nephroblastoma, evaluate the situation of the contralateral kidney well, and can determine the scope of the tumor and metastasis, which has important significance for the staging of the tumor and guiding the clinical development of the treatment plan .
