     Pediatric Radiology CasesMost likely etiology:

    neoplastic  

     
     Pediatric Radiology CasesHistory:

    Male, 16 years, gynecomastia on both sides and increased estradiol values. Testicles were unremarkable without clinical difference in size or palpatory findings.  

     
     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease :

    -rare tumor: 1% of all testicular tumors
    -the most Leydig-cell tumors produce testosterone or estradiol
    -in children prior to puberty, a development of precocious puberty is seen. In adults/adolescents, gynecomastia is seen due to the estrogen production.
    -seldom malignant, particularly in children. Malignant Leydig-Cell tumors metastasize only many years after surgery in retroperitoneal lymph nodes.  

     
     Pediatric Radiology CasesRadiological findings:


    Ultrasound 1 <- view Ultrasound 1

    Ultrasound 1: (13MHz-Probe) right testicle, longitudinal: 11 x 12 x 13mm, intratesticular, slightly lower in echoes, smooth edged mass with slight hyperperfusion in the border.




    Ultrasound 2 <- view Ultrasound 2

    Ultrasound 2: (13MHz-Probe) right testicle, horizontal in comparison: 11 x 12 x 13mm, intratesticular, slightly lower in echoes, smooth edged mass with slight hyperperfusion in the border.




    MRI 1 <- view MRI 1

    MRI 1: T1-weighted before contrast: homogenic, barely demarcated mass in the right testicle.




    MRI 2 <- view MRI 2

    MRI 2: T1-weighted after application of contrast with fat saturation: Homogenic, smoothly demarcated mass with obvious contrast enhancement.




    MRI 3 <- view MRI 3

    MRI 3: T2-weighted, transversal: Homogenic, smoothly demarcated mass with decreased signal.

     

     
     Pediatric Radiology CasesDiagnosis confirmation:

    Surgery / Histo  

     
     Pediatric Radiology CasesWhich DD would be also possible with the radiological findings:

    Other testicular tumors: i.e. Testicular carcinoma, teratoma, testicular lymphoma  

     
     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other :

    - in this patient, surgery was done 6 months earlier, which was able to save the testicles: Enucleation of the tumor with a seam of normal testicular tissue.
    -there is an area of low echoes as a representation of a postoperative defect in the area of resection.
    -sonographically and clinically involution of gynecomastia
