OBJECTIVE: This report describes the imaging characteristics of focal posttransplantation lymphoproliferative disorder. CONCLUSION: 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.
