title: [The Leydig-cell testicular tumor. A case report with magnetic resonance images].
abstract: OBJECTIVE
  An additional case of testicular Leydig cell tumor in a young man is reported. The clinical presentation included gynecomastia and a testicular mass.
  
  
  RESULTS
  Hormonal studies, testicular US and high resolution MRI were performed before orchidectomy. The histopathological findings were consistent with Leydig cell tumor. A CT scan revealed no metastasis. The patient is clinically disease-free 18 months after orchidectomy.
  
  
  CONCLUSIONS
  High resolution MRI must be performed only when clinic and US findings are discordant.
