18 F-FDG PET/CT in Renal Allograft Tuberculosis Mimicking as Posttransplant Malignancy

Clin Nucl Med. 2024 Feb 1;49(2):e52-e53. doi: 10.1097/RLU.0000000000004977. Epub 2023 Dec 4.

Abstract

The most common complications after the renal transplant are infections and malignancies, including posttransplant lymphoproliferative disorders. Tubercular infection in renal allograft recipients is a relatively rare entity. However, nonspecific constitutional symptoms often delay diagnosis, leading to significant morbidity and mortality. We present the 18 F-FDG PET/CT findings in a patient with renal allograft tuberculosis who had clinical and imaging suspicion of posttransplant lymphoproliferative disorder or renal cell carcinoma. Histopathology from the renal lesion revealed tuberculosis.
