Post-transplantation Lymphoproliferative Disorder in Transplanted Liver: A Case Report

ABSTRACT

Post-transplantation lymphoproliferative disorder occurs in transplant recipients in whom immunosuppressivetherapy has compromised the immune system. In patients who have undergone transplants, suppressor T lymphocytefunction is suppressed, leading to unbridled B lymphocyte proliferation. We encountered a case withpost-transplantation lymphoproliferative disorder which manifested as a focal hepatic mass in transplanted liver.This mass was isoechoic, with a peripheral hypoechoic halo on ultrasonogram, while on all three phases of helicalCT scan low attenuation without contrast enhancement was seen.
