title: [Testicular tumor. Ultrasonography study].
abstract: OBJECTIVE
  The present study reviews the diagnostic criteria of testicular ultrasonography.
  
  
  METHODS
  Our experience and data available at our institution and in the literature were reviewed. The US patterns directly or indirectly related to testicular tumors and the lesions that may mimic these tumors are analyzed. The utility of CT and MRI is also discussed.
  
  
  RESULTS
  The sensitivity of US in testicular tumors was 100%. Its specificity was lower and was limited by the technique which is operator-dependent. Most of the testicular tumors were hypoechoic and this was a common feature of seminoma.
  
  
  CONCLUSIONS
  The rational use of the US patterns together with the clinical and biological findings are useful in making the diagnosis in tumors with atypical patterns or those found in special groups of patients.
