Waldenström macroglobulinemia presenting as a renal or perirenal mass: clinical and radiographic features.

Manifestations of macroglobulinemic lymphoma include lymphadenopathy, splenomegaly and bone marrow involvement. Renal presentations are unusual and complications of renal function are even less frequent. A review of all patients diagnosed with Waldenström macroglobulinemia at our institution from January 1987 to December 1993, revealed 4 cases (6%) with renal presentations. We describe these cases with their associated clinical and radiologic features.
