The computed tomography (CT) and ultrasound findings in 18 patients (35 kidneys) with non-Hodgkin lymphoma involving the kidneys are presented. Renal involvement was bilateral in 13 patients. The most common presentation was that of multiple intraparenchymal nodules (15 kidneys). Other types of involvement included direct invasion from contiguous retroperitoneal lymph node masses (nine kidneys), solitary renal masses (five kidneys), and diffuse infiltration (two kidneys). On CT most of the lesions were of homogeneous tissue density. Ultrasonographically the renal masses were hypoechoic. We believe that CT is the procedure of choice for the detection and follow-up of renal lymphoma.
