Abstract:
Objective To analyze the clinical and MRI images of testicular teratoma in children and to compare with pathological results.Methods The clinical and MRI data of 12 children with testicular teratoma confirmed by pathology were analyzed retrospec-tively.Results Of the 12 cases,6 cases were on the left testicle and 6 cases were on the right testicle.The clinical manifestations were all painless testicle enlargement.Of these,6 cases were accompanied by a slight increase of neuron-specific enolase,3 cases had increased alpha-fetoprotein(AFP),10 cases were mature teratoma,and 2 cases were immature teratoma.MRI findings showed that the lesions in 6 cases were cystic,with long T1 and T2 signals as the main signals,no reduction in lipid pressure image signals,no enhance-ment on the enhanced scan,and low signal on diffusion weighted imaging(DWI).The other 6 cases were cystic-solid lesions,mainly with mixed T1 and T2 signals,and showed uneven high signal on DWI.The cystic components were not enhanced on the enhanced scan,and the solid components were mildly to significantly enhanced.Among them,3 cases were accompanied by irregular flaky short T1 and long T2 signals,decreased lipid pressure image signals,1 case was accompanied by speckle long T1 and short T2 signals.And the envelope intact in all 12 cases.Conclusion The MRI findings of testicular teratoma in children are mostly cystic lesions,with few signs of fat and calcification,and no obvious invasion of peripheral structures.AFP examination is helpful for diagnosis.
