摘　　要：目的研究分析电子计算机断层扫描(CT)、超声对小儿睾丸肿瘤的临床诊断价值。方法选取2014年1月至2017年12月我院经手术病理证实的77例睾丸肿瘤的患儿作为研究对象,分析所有患儿的病理及临床资料,探讨CT及超声的临床诊断价值。结果在超声征象中,两组患儿肿瘤形状规则、钙化、囊变、肿块内部回声以及血流情况,差异具有统计学意义(χ^2值分别为9.350、8.241、36.543、4.720、6.124,均P<0.05),两组患儿肿瘤回声均匀的差异性不具有统计学意义(χ^2=3.052,P>0.05)。在CT征象中,比较不同性质肿瘤形态、囊变、实性部分强化、供血动脉增粗、内部纤维间隔强化、不对称精索血管强化征及肿块内部密度,差异均具有统计学意义(χ^2值分别为24.514、5.469、6.124、11.717、12.413、14.198、13.246,均P<0.05),两组患儿钙化情况差异不具有统计学意义(χ^2=1.751,P>0.05)。超声与CT两种检查方法检出率均达到100%,其中CT检查的定性准确率达到72.73%。结论超声能够较好发现睾丸肿块,准确率较高,对微小钙化敏感度较高,但对各种病理类型鉴别率较低。CT能够显示肿瘤的整体轮廓,分析肿块的强化情况以及转移情况。CT与超声在小儿睾丸肿瘤诊断中具有不同优势,二者结合可发挥最大效能。Objective To analyze the clinical diagnostic value of computerized tomography(CT) and ultrasound in pediatric testicular tumors.Methods A total of 77 children with testicular tumors confirmed by surgery and pathology between January 2014 and December 2017 were enrolled as subjects to analyze the pathology and clinical data.The clinical diagnostic value of CT and ultrasound was explored.Results In the ultrasound signs,there was statistical significance in shape,calcification,cysts,internal echo and blood flow(χ^2 value was 9.350,8.241,36.543,4.720 and 6.124,respectively,all P<0.05),but no statistically significant difference was found in echo uniformity between two groups(χ^2=3.052,P>0.05).In CT signs,the differences were statistically significant in tumor morphology,cystic changes,solid partial enhancement,thickening of blood supply artery,internal fibrosis enhancement,asymmetric choroidal vascular enhancement and internal density of tumor(χ^2 value was 24.514,5.469,6.124,11.717,12.413,14.198 and 13.246,respectively,all P<0.05).There was no significant difference in calcification between two groups(χ^2=1.751,P>0.05).The accuracy of both ultrasound and CT examination methods reached 100%,and the qualitative accuracy of CT examination reached 72.73%.Conclusion Ultrasound can detect testicular masses with high accuracy and is highly sensitive to microcalcification,whereas it has a low discrimination rate for various tumor pathological types.CT can show the overall outline and analyze the tumor mass reinforcing and metastasis.CT and the ultrasound have different advantages in the diagnosis of pediatric testicular tumors.Combining these two methods can maximize their effectiveness.
