title: [Scintigraphic diagnosis of crossed renal ectopia].
abstract: OBJECTIVE
  Crossed renal ectopia is an uncommon congenital anomaly with little or no clinical repercussion. An empty renal fossa is not an infrequent ultrasound finding and an anomalous contralateral ectopic kidney can be seen occasionally.
  
  
  RESULTS
  We report on three clinical cases with an empty renal fossa detected by ultrasound. Scintiscanning with 99mTc DMSA permitted precise diagnosis of the existing malformation.
  
  
  CONCLUSIONS
  99mTc DMSA permits precise diagnosis of the empty renal fossa, type of malformation, functional status of the ectopic kidney and the status of its parenchyma.
