Scintigraphic detection of a disseminated synovial lymphoma in a postrenal transplant patient.

Post-transplant lymphoproliferative disease is a recognized complication of immunosuppressive therapy, however, articular lymphomas involving the synovlum are very rare. Disseminated synovial lymphoma of the knee with hepatic involvement in a patient after renal transplant was suggested on bone/gallium scintigraphy and confirmed by synovial biopsy. Gallium scanning thus was instrumental in the evaluation, staging, and proper treatment of this rare condition.
