Left renal mass seen on CT. ABDOMEN:LIVER, BILIARY TRACT: Mildly nodular liver contour. No suspicious liver lesion. Patent vasculature. Cholelithiasis without cholecystitis.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Stable right renal superior pole 5.7 x 5 5 cm cyst (series 4/12). Anteriorly there is a small mural nodule which does not demonstrate enhancement (series 4/12).In the anterior cortex of the right kidney interpolar region is a stable 2.9 x 1.9 cm angiomyolipoma (series 1000/37).Immediately inferior is a 3.1 x 2.4 cm intrinsically T1 hyperintense (series 10/43) nonenhancing lesion compatible with a hemorrhagic/proteinaceous cyst.In the left kidney interpolar region posterior cortex there is a 1.3 cm T2 hypointense lesion. The lesion demonstrates mild postcontrast enhancement. There is also signal loss on the T2-weighted fat-suppressed images (series 4/19). The lesion does demonstrate some signal loss on out of phase imaging suggesting intra-voxel fat (series 1002/49). RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Indeterminate 1.3 cm left renal interpolar region lesion is stable in size. We favor that this represents an angiomyolipoma. Possibility of Renal cell carcinoma cannot be excluded. However, continued imaging follow-up is recommended.2.Stable right renal angiomyolipoma measuring 2.9 cm.3.Simple and minimally complex right renal cysts.4.No suspicious liver lesion.
