Early Post-transplant Lymphoproliferative Disease in the Donor Ureter Without Systemic Involvement: A Case Report

Treatment of Epstein-Barr Virus-Related Post-Renal Transplantation Development of Diffuse Large B Cell Lymphoma of the Distal Ureter: A Case Report

Posttransplant lymphoproliferative disorder with involvement of the donor urogenital tissue is a rare and serious complication of solid organ transplant. We report an adult kidney transplant recipient who developed the diffuse large B cell lymphoma of the distal ureter in the setting of new allograft nephropathy. Early intervention, reduction of immunosuppression, surgical reconstruction and chemotherapy salvaged the allograft kidney and averted a fatal outcome. The renal function recovered to the baseline with creatinine ranging between 1.3 and 1.5. The patient did not require dialysis at any point after ureteral stent placement and reconstructive surgery. In addition, the case highlights the importance of multidisciplinary management involving transplant nephrology, oncology, transplant surgery, and urology in such a complicated disease process.

Imaging features of immune-mediated genitourinary disease

PURPOSE

Imaging features of immune-mediated genitourinary diseases often overlap, and the same disease may manifest in different ways, so understanding imaging findings in the context of the patient's entire clinical picture is important in providing the correct diagnosis.

METHODS

In this article, diseases mediated by the immune system which affect the genitourinary system are reviewed. Examples of immune-mediated genitourinary disease including IgG4-related disease, post-transplant lymphoproliferative disorder, immunodeficiency-associated lymphoproliferative disorder due to immunosuppressive and immunomodulatory medications, lymphoma, leukemia, myeloma, amyloidosis, and histiocytosis.

RESULTS

Clinical and imaging features will be presented which may help narrow the differential diagnosis for each disease.

CONCLUSION

Recognition of immune-related genitourinary disease is important for appropriate medical management as they may mimic other diseases both by imaging and clinical presentation.
