Questionable right renal lesion on CT scan. History of non-small cell lung cancer stage IA. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, signal intensity and size. No suspicious liver lesion or biliary ductal dilatation. Normally distended gallbladder.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: Homogeneous left adrenal nodule measuring 1.5 x 1.2 cm (series 12/176), stable from recent prior and decreased from the 2005 study.KIDNEYS, URETERS: In the dorsal aspect of the right renal inferior pole there is a 1.2 cm partially exophytic lesion demonstrating extrinsic T1 weighted hyperintensity without evidence of postcontrast enhancement compatible with a proteinaceous/hemorrhagic cyst. Immediately inferiorly within the renal cortex there is an arterially enhancing 1.2 cm round lesion with intrinsic T2 weighted hyperintensity without macroscopic fat, suspicious for a renal cell carcinoma, clear cell type. No evidence of invasion into the collecting system or renal vein. No significant locoregional lymphadenopathy. The 1.4 cm exophytic lesion described on the recent prior CT in the left inferior pole demonstrates intrinsic macroscopic fat signal intensity and is compatible with a benign entity such as angiomyolipoma.No hydroureteronephrosis.RETROPERITONEUM, LYMPH NODES: Small peripancreatic lymph nodes measuring less than 1 cm.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. 1.2 cm heterogeneously enhancing right inferior pole lesion suspicious for RCC, clear cell type. Adjacent 1.2 hemorrhagic/proteinaceous cyst.2. Left renal exophytic lesion described on recent CT demonstrates intrinsic macroscopic fat signal intensity and is compatible with a benign entity such as an angiomyolipoma, measuring 1.4 cm. It is stable from the CT portion of the PET/CT dated 10/8/2015.3. Stable left adrenal nodule; however, it does not demonstrate MR signal characteristics of a lipid rich adenoma.
