No suspicious focal hepatic lesion.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: The 1.6 x 1.6 cm round circumscribed exophytic mass arising from the inferior pole of the left kidney is unchanged in size compared to the recent prior CT, though is slightly enlarged compared to the CT on 10/16/2014.

T2 hypointense 1.6 cm mass at the inferior pole of the left kidney with internal enhancement as above, suspicious for renal cell carcinoma, particularly papillary subtype given background of T2 hypointense signal.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
