摘要
目的 对比误诊病例,探讨儿童肾母细胞瘤的CT特征,以提高对肾母细胞瘤的认识和诊断的准确性。方法 收集我院腹部CT诊断为儿童肾母细胞瘤52例,按手术病理结果分为肾母细胞瘤组39例与误诊组13例。回顾性审阅CT图像,记录肿瘤最大径,辨别有无包膜、中等度强化、出血、钙化、坏死囊变、残肾征及蟹足征等CT征象,统计分析比较两组一般资料、临床首发症状及CT征象的差异。结果 1.一般资料及临床首发症状上两组表现类似,经χ^(2)检验均无统计学差异。2.肾母细胞瘤组中包膜、“残肾征”和“蟹足征”出现率比误诊组高,且存在统计学意义;肿瘤最大径两组间无统计学差异,同时中等度强化、出血、钙化以及坏死囊变的发生率组间比较均无统计学差别。3.儿童肾母细胞瘤的定位征象具有特征性,有助于减少误诊。结论 包膜、“残肾征”和“蟹足征”是肾母细胞瘤较为特征性的CT表现,结合肾母细胞瘤的定位特点,可以降低误诊率。同时需要注意与其他类型少见的肾恶性肿瘤鉴别。
Objective Comparing misdiagnosed cases,to study the CT features of renal tumor in children,in order to improve the recognition of nephroblastoma and diagnostic accuracy.Methods 52 cases of nephroblastoma in children diagnosed by abdominal CT in our hospital were collected.According to the surgical and pathological results,they were divided into 39 cases in nephroblastoma group and 13 cases in misdiagnosis group.CT images were reviewed,The maximum diameter of the tumor was recorded,and the CT signs such as capsule,moderate enhancement,bleeding,calcification,necrotic cystic change,residual kidney sign and crab foot sign were distinguished.The general data,first clinical symptoms and CT signs of the two groups were statistically analyzed and compared.Results 1.The general data and first clinical symptoms of the two groups were similar,and there was no statistical difference between them byχ^(2)-test.2.CT signs of the tumor,the incidences of capsule,"residual kidney sign"and"crab foot sign"in nephroblastoma group were higher than those in misdiagnosis group,and the difference was all statistically significant;There was no significant difference in the maximum diameter of tumor between the two groups,while there was no significant difference in the incidence of moderate enhancement,bleeding,calcification and necrotic cystic change.3.The locational signs of children's nephroblastoma were characteristic and helpful to reduce misdiagnosis.Conclusion Capsule,"residual kidney sign"and"crab foot sign"were the characteristic CT manifestations of nephroblastoma.Combined with the locational signs of nephroblastoma,the misdiagnosis rate would be reduced,while it also needed to be differentiated from other rare types of renal malignancies.
