CT
A well-defined exophytic mass lesion measuring 4.5 x 4.7 x 6.6 cm is seen along the mid and lower pole of the right kidney. This lesion has an average density of 26, 43 and 85 Hounsfield units on plain, arterial & portovenous phase imaging respectively. Right renal vein is patent and well-opacified. IVC is not well-opacified, likely due to early venous phase imaging. There is no evidence of extension of this lesion into the renal collecting system. No significant locoregional lymphadenopathy or distant metastases is noted.
Multiple surgical clips are seen around the stomach and distal small bowel loops (past history of biliopancreatic surgery). Status post cholecystectomy. An intrauterine contraceptive device (IUCD) is seen in place.
