Bilateral Primary Renal Lymphoma Presenting with Acute Renal Failure

Non-Hodgkin's lymphoma is a multisystem disease presenting with painless lymph node involvement in patients between 40 and 70 years of age. Kidney failure can be seen in about 10% of lymphoma patients due to different reasons. However, renal failure caused by lymphomatous parenchymal infiltration of the kidneys is very rare. In this study, we present a case of bilateral primary renal lymphoma presenting with acute renal failure.
