The patient is a 61-year-old man with advanced, systemic non-Hodgkin's lymphoma, presenting with renal failure and microscopic hematuria of several weeks duration. Pertinent history is remarkable for chronic NSAID use. Review of systems is remarkable for edema.
Kidneys are bilaterally enlarged sonographically. The clinical differential is lymphomatous infiltration of kidneys versus interstitial nephritis secondary to NSAID use.
