title: [Kidney pelvis hemangioma as a cause of hematuria].
abstract: Kidney hemangiomas are congenital vascular anomalies with an unknown ethiology. They are considered as benign tumours with a poor clinic expression (hematuria or ureteric colic, which is associated to the drop of clots in the urinary tract).
  
  
  OBJECTIVE
  To expound a case of unilateral severe hematuria in a young woman with a restless past medical history, due to a pelvic left kidney hemangioma.
  
  
  METHODS
  Clinic case of a sixteen years old woman, no relevant past medical history, presented with an anaemizing gross hematuria and passing vermiform clots. As diagnostic techniques we used ultrasonography, excretory urography, cystourethroscopy, CT, angiography and nuclear imaging. Surgery (flank nephectomy) was needed for treatment.
  
  
  RESULTS
  Pathology report: submucosal vascular proliferative process in kidney pelvis composed by blood vessels, suggesting haemangioma.
