History of hepatitis C. Renal mass seen on ultrasound. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, size and signal intensity. There are numerous simple and minimally complex bilobar cysts. No focal suspicious lesion. Normal distended gallbladder. No biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: Approximately 5 mm distal pancreatic body cystic lesion likely communicates with the main pancreatic duct, compatible with a sidebranch IPMN without suspicious imaging features. Additional punctate cystic foci, likely small IPMNs.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Bilateral cysts. In the right interpolar region there is a 5.9 x 6.0 x 5.4 cm mass demonstrating heterogeneous T2-weighted signal predominantly isointense with the renal parenchyma and a hypointense capsule. The lesion demonstrates mild enhancement. It extends into the perirenal fat but not beyond the pararenal fascia. No locoregional lymphadenopathy, significant extension into the collecting system or renal vein involvement.There are several punctate subcentimeter intrinsically T1 weighted hyperintense foci in the left kidney likely representing proteinaceous/hemorrhagic cysts.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.
6 cm right interpolar mildly enhancing mass is suspicious for a renal cell carcinoma specifically a papillary subtype given its relatively low T2-weighted signal intensity and hypoenhancement. No evidence of renal vein invasion or locoregional lymphadenopathy. Bilateral hepatic and renal simple/minimally complex cysts.
