title: Focal posttransplantation lymphoproliferative disorder at the renal allograft hilum.
abstract: OBJECTIVE
  This report describes the imaging characteristics of focal posttransplantation lymphoproliferative disorder.
  
  
  CONCLUSIONS
  Posttransplantation lymphoproliferative disorder may be limited to the allograft. A focal complex mass in the renal allograft hilum surrounding the main renal blood vessels is a common finding and can be visualized with sonography. MR imaging can help increase diagnostic confidence.
