title: Traumatic rupture of angiomyolipoma: a case report.
abstract: OBJECTIVE
  To describe a case of traumatic rupture of renal angiomyolipoma (AML).
  
  
  METHODS
  The images and clinical data of the present case are presented.
  
  
  RESULTS
  A rare case with exuberant clinical presentation of a perirenal hematoma resulting from traumatic rupture of renal AML is presented with a brief review of the role of ultrasound (US) and body-CT in the diagnosis of this pathology and its complications.
  
  
  CONCLUSIONS
  Whenever there is a collection detected by US in the various anatomic renal spaces, in a patient with flank pain and low hemoglobin shortly after abdominal trauma, it is advisable to perform abdominal CT and search for a hematoma. Small amounts of fat, detected by US and body-CT, may lead to the diagnosis of an underlying AML that can rupture, even in the case minor forces are applied to the kidney.
