Four patients with renal lymphoma were evaluated by computed tomography and presented the following different manifestations: (a) multiple large and small nodules infiltrating each kidney; (b) a single large renal mass extending into the perirenal space; (c) diffuse infiltration of both kidneys; and (d) lesion of the renal hilus encasing the renal pelvis and proximal ureter of one kidney. Computed tomography is a sensitive, noninvasive imaging modality that should be performed early in the course of disease in patients with known or suspected lymphoma.
