Posttransplantation lymphoproliferative disorder (PTLD) is a challenging complication associated with organ transplantation and is usually fatal if untreated. We describe the case of a transplant recipient who presented with rapidly progressive cranial nerve palsies due to PTLD that originated in the sphenoid sinus. In this case, the clinical and radiologic presentation of PTLD mimicked invasiv...

INTRODUCTION To establish the role of positron-emission tomography (PET)-computed tomography (CT) in post-transplant lymphoproliferative disorder (PTLD) patients, compared to conventional imaging (ultrasonography/CT/magnetic resonance imaging) in relation to its accuracy, sensitivity and specificity. METHODS 30 patients (26 males and 4 females), with a median age of 49.5 (range 18-74) years, ...

Early diagnosis of Epstein-Barr Virus (EBV)-associated posttransplant lymphoproliferative disease (PTLD) is important because many patients respond to reduction in immunosuppression, especially if PTLD is detected at an early stage. Previous studies have found elevated EBV DNA levels in blood from patients with PTLD, but these assays required isolation of cellular blood fractions and quantitati...

Epstein-Barr virus (EBV) viremia (EV) in pediatric solid organ transplant (SOT) recipients is a significant risk factor for posttransplant lymphoproliferative disease (PTLD) but not all patients with EV develop PTLD. We identify predictive factors for PTLD in patients with EV. We conducted a retrospective chart review of all pediatric SOT recipients (0 to 21 y) at a single institution between 2...

Epstein-Barr virus (EBV) early-antigen (EA) serologic profile was examined in conjunction with peripheral blood EBV DNA load, to assess its value in evaluating the risk of developing posttransplantation lymphoproliferative disease (PTLD). The cohort included 26 pediatric recipients of solid-organ transplants, 6 of whom developed PTLD. All 6 patients had high peripheral blood EBV DNA loads. Of t...

Patients after solid organ transplantation (SOT) carry a substantially increased risk to develop malignant lymphomas. This is in part due to the immunosuppression required to maintain the function of the organ graft. Depending on the transplanted organ, up to 15% of pediatric transplant recipients acquire posttransplant lymphoproliferative disease (PTLD), and eventually 20% of those succumb to ...

Post-transplant lymphoproliferative disorder (PTLD) is one of the most common malignancies after solid organ or allogeneic stem cell transplantation. Most PTLD cases are B neoplasias carrying Epstein-Barr virus (EBV). A therapeutic approach reduction immunosuppression to allow T cells develop and combat EBV. If this not effective, approaches include immunotherapies such as monoclonal antibodies...
