title: A Rare Case of Polyorchidism: Four Testes.
abstract: BACKGROUND
  Polyorchidism or supernumerary testis means more than two testes. It is very rare and to the best of our knowledge, there have been only about 200 cases reported.
  
  
  METHODS
  In this case report we want to present radiological features and assessment of a patient with four testicles.
  
  
  CONCLUSIONS
  If the vascularity and echogenicity of the scrotal mass is similar with the normal testis parenchyma, multitestis should be considered. The MRI might not provide us with additional information to USG or CDUSG, thus it is not necessary to perform it if there is no suspicion of malignancy.
