title: [Spontaneous bleeding from renal cyst as a cause of acute anemia].
abstract: OBJECTIVE
  To report a case of a simple left renal cyst in a patient who presented with spontaneous pain and acute anemia due to intracystic hemorrhage.
  
  
  METHODS
  Diagnostic imaging techniques such as assessment of the urinary tract with contract medium, ultrasound CT and MRI were utilized for correct preoperative diagnosis and surgical management.
  
  
  RESULTS
  The patient was able to return to normal active work.
  
  
  CONCLUSIONS
  Rarely as in the case described renal cysts can collect blood at the expense of the renal parenchayma. Ultrasound and CT are very useful diagnostic imaging techniques in renal pathologies.
