A lobulated soft tissue density mass lesion is seen at the mid-pole of the right kidney. The lesion measures 24 x 34 x 44 mm and has an average density of 25, 31, 42 and 45 HU on non-contrast, renal cortical, parenchymal and excretory phases, respectively. The lesion has a few tiny peripheral calcification foci along its inferomedial aspect, invading the intrarenal collecting system. Mild dilatation of the right intrarenal collecting system is noted. Two small calculi are seen in the right proximal ureter. The renal vein and IVC are patent. No evidence of invasion is seen in the adjacent structures. No lymphadenopathy is seen.
Tiny non-enhancing hypodensity measuring 2 mm is seen in segment VII of the liver, likely a cyst. No other focal hepatic pathology is seen.
Retroaortic left renal vein (type 1).
A few old rib fractures; otherwise, no suspicious osseous pathology is seen in the visualized skeleton.
