title: [Crossed renal ectopia: radiological possibilities of helicoidal CAT].
abstract: OBJECTIVE
  To evaluate the diagnostical possibilities of helicoidal CAT in crossed renal ectopy (CRE) and review 36 cases published in Spain, including our 3 new patients.
  
  
  METHODS
  We present two women and a man aged between 54 and 82 who were diagnosed of left CRE. One of them showed an ureterocele and other one presented a splenic angiosarcoma.
  
  
  CONCLUSIONS
  Main embriological theories, clinical presentation, associated anomalies and different radiological systems used in the diagnosis of this infrequent congenital malformation are evaluated.
