本文报告B 型超声检查小儿常见腹膜后肿瘤41例。声象图可显示肿瘤形状、大小及其与眦邻器官的关系,观察肿瘤来自肾内或肾外,结合肿瘤边界和内部回声结构的差异,超声图象诊断为肾母细胞瘤、成神经细胞瘤和腹膜后畸胎瘤共37例(占90%),均经手术及病理检查证实。少数巨大腰部肿块与肾脏关系显示不清病例,确定肿瘤类型仍有困难,此时需结合大血管被推移、淋巴结及肝脏内转移病灶等其他超声图象改变,参考X 线尿路造影和临床生化检查资料全面分析再下结论。
This report reports 41 cases of common retroperitoneal tumors in children by B-mode ultrasound. The sonogram can show the shape and size of the tumor and its relationship with the adjacent organs. The observation of the tumor from the inside of the kidney or the kidney, combined with the difference of the tumor boundary and the internal echo structure, the diagnosis of nephroblastoma and neuroblastoma Tumor and retroperitoneal teratoma in a total of 37 cases (90%), were confirmed by surgery and pathology. A few large lumbar masses and renal disease showed unclear cases, to determine the type of tumor is still difficult, this time with the need to move the large vessels, lymph nodes and liver metastases and other lesions change other ultrasound images, refer to X-ray urography and clinical biochemistry Check the data a comprehensive analysis and then concluded.
