title: [Clinical assessment and treatment of spontaneous perirenal hemorrhage].
abstract: OBJECTIVE
  Four cases of spontaneous perirenal hemorrhage are reviewed, with special reference to the clinical features, diagnosis and treatment.
  
  
  RESULTS
  Two were due to tumor (sarcomatoid carcinoma and angiomyolipoma) and the rest were secondary to renal lesions. All patients underwent nephrectomy due to hemodynamic instability.
  
  
  CONCLUSIONS
  Nephrectomy appears to be the best treatment since this condition may arise from a malignant tumor which, to date, cannot be determined by any diagnostic method.
