Perinephric space infiltration of renal lymphoma. Axial CT of the abdomen (a) demonstrates an infiltrative homogenous mass (arrows) in the left retroperitoneum enveloping the left kidney with preservation of the left renal parenchymal anatomy. Additional thickening of Gerota’s fascia and Zuckerkandl fascia as well as retroperitoneal tumor infiltration along the pancreatic tail and splenic hilum are present (b). Note the preservation of normal caliber splenic vein and artery (arrowheads). Due to the unusual tumor morphology, the left renal mass was biopsied and consistent with diffuse large B-cell lymphoma
