FDG PET/CT Findings of the Recurrent Posttransplantation Lymphoproliferative Disorder in a Pediatric Liver Transplant Recipient With Right Leg Pain as the Only Complaint

摘要

The most commonly observed symptoms of posttransplantation lymphoproliferative disorder (PTLD) after a liver transplantation were diarrhea and fever. Although PTLD can involve bones, bone pain is a rare manifestation of PTLD, much less to say a sole presentation. We report a case of a pediatric patient with recurrent PTLD after liver transplantation, whose only complaint was right tibial pain. FDG PET/CT revealed not only hypermetabolic activity in the right proximal tibia but also in many other parts of the body. Recurrent PTLD was confirmed after bone biopsy.
