Reason: further charaterization of renal mass described on recent chest CT; avoiding iodine/gadolinium given CKD History: incidental renal mass ABDOMEN:LIVER, BILIARY TRACT: Subcentimeter T2 hyperintensity in the left hepatic lobe (4/16) is incompletely characterized without intravenous contrast. SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: 6.3 x 5.0 cm left upper quadrant lesion seen on CT appears to arise from the left adrenal gland and not the kidney (6/92). On the prior CT, this lesion had regions of fat density. These regions are hyperintense on T1-weighted images, consistent with macroscopic fat. There is loss of signal on out of phase images suggesting microscopic fat. Overall, these imaging characteristics are suggestive of an adrenal myelolipoma.KIDNEYS, URETERS: No significant abnormality noted.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.
Lesion described on prior CT likely represents a left adrenal myelolipoma.
