Reason: renal cancer and abdominal mass History: as above; please compare with previous MRI ABDOMEN:LIVER, BILIARY TRACT: Subcentimeter T2 hyperintensities are stable and likely represent cysts. No suspicious hepatic lesions.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Postsurgical changes from partial resection of right moiety and total resection of left moiety of horseshoe kidney. Previously described tumor involving the right midpole and tumor thrombus within the right renal vein is no longer discretely measurable, decreased in size from prior. The right renal vein appears patent. There is mild soft tissue irregularity along the medial margin of the right lower pole (series 10, image 292) which is nonspecific and may reflect treatment changes versus residual disease. Right lower pole cyst is unchanged.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.
Interval decrease in size of the tumor involving the right midpole as well as right renal vein tumor thrombus. Mild soft tissue irregularity along the medial margin of the right lower pole may reflect treatment changes or minimal residual disease. Currently, no discretely measurable tumor.
