目的评价ＩＶＰ．ＵＳ．ＣＴ．对儿童肾母细胞瘤的诊断价值。方法回顾分析了１１例经手术、病理证实为肾母细胞瘤的ＩＶＰ ＵＳ．ＣＴ．表现。结果 ＩＶＰ肾盂不显影 ３例。显影 ８例，表现为肾盂肾盏推移变形伴肾盏破坏。 ＵＳ显示实质不均质高回声 ６例，低回声４例，无回声１例。ＣＴ表现不均匀强化的实质性肿瘤伴坏死，残存肾实质呈“新月形”强化为典型表现。显示腹膜后淋巴结转移４例、右眼眶骨转移１例。结论采用二种或二种以上检查方法，能提高术前诊断的准确性。
Purpose To evaluate IVP. US. CT. Diagnostic value of children’s nephroblastoma. Methods Retrospective analysis of 11 cases of IVP US confirmed by surgery and pathology as nephroblastoma. CT. which performed. Results IVP renal pelvis does not develop in 3 cases. Development in 8 cases, the performance of the renal pelvis callus deformity with renal calculus damage. US showed virtually inhomogeneous hyperechoic in 6 cases, hypoechoic in 4 cases and anechoic in 1 case. CT showed heterogeneous enhancement of substantial tumor with necrosis, residual renal parenchyma was “crescent” to strengthen the typical performance. 4 cases showed retroperitoneal lymph node metastasis, right orbital bone metastasis in 1 case. Conclusion Using two or more than two kinds of examination methods, can improve the accuracy of preoperative diagnosis.
