Six patients had nine kidneys with lymphoma. Five patients (83%) had non-Hodgkin lymphoma, and three (50%) bilaterally. There were multiple nodules in four kidneys (44%). The lesions were changeful in the course. Gallium scintigraphy showed abnormal uptakes. Magnetic resonance imaging was examined in one case. The lesions were hypovascular in the angiographies. Inflammation is one of the different diagnosis.
