History of left renal inferior pole oncocytoma, status post left partial nephrectomy. Evaluate left upper pole lesion. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, size, signal intensity and enhancement. No focal suspicious lesion, biliary ductal dilatation or vascular abnormality.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Simple appearing bilateral cysts. Several too small to characterize left renal T2-weighted hyperintensities, likely cysts. Postsurgical changes from a left inferior partial nephrectomy.The mildly T2 weighted hypointense lesion in the superior pole of the left kidney measures 1.5 x 1.2 x 1.7 cm (series 9/19), compared to 1.6 x 1.2 cm previously. There are mild associated exophytic cystic changes. There is significant intrinsic T1 weighted signal intensity. There is suspected mild post-contrast enhancement of the lesion.
