RESUMO
Objective To analyzed imaging features of testicular and epididymal tumors or inflammatory nodes in children and to improve its diagnostic accuracy.Methods 13 cases underwent ultrasonography,of them,plain CT scan in 10 cases,enhanced CT scan in6 cases.Its signs were retrospectively analyzed and compared with surgical and pathological results.Results On ultrasonography,theinhomogenous and different echo could be viewed in 13 cases,color Doppler flow imaging was abundant in 8 masses,3 cases with littler,empty blood flow in 2 cases and retroperitoneal lymphatic metastasis were viewed in 2 cases.On plain CT scan,masses were mixed density in 4 cases,calcification could be seen within tumor in 3 cases,masses were soft tissue or main soft tissue density in 6 cases.Contrast-enhancedCT scan displayed obviously and inhomogenously in 4 cases,lightly enhancment in 1 case and no enhanced in 1 case.By surgical andpathological confirmed,3 were mature treatomaes,1 was immaturity teratoma,4 were yolk sactumor,3 were inflammatory nodes,1 wasrhabdomyosarcoma and 1 was cystic lymphangioma.Conclusion Each kind of testicular tumors in children has its owns CT and UScharacteristics.In combination of CT and US can carry high diagnostic accuracy.
