Primary Central Nervous System Posttransplant Lymphoproliferative Disorder After Kidney Transplant

Abstract

Primary central nervous system posttransplant lymphoproliferative disorder is a rare complication of solid organ transplantation, with increasing incidence in children given a steady rise in pediatric solid organ transplants. Given similar imaging appearance to many opportunistic infections, a high degree of awareness is required for prompt and early diagnosis. We report a case of primary central nervous system posttransplant lymphoproliferative disorder presenting as a single rim enhancing lesion with central restricted diffusion mimicking an intracranial abscess.
