History of colon cancer status post resection with adrenal nodule seen on CT. ABDOMEN:LIVER, BILIARY TRACT: Normal liver morphology without a focal lesion, biliary ductal dilatation or vascular abnormality. Normally distended gallbladder.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: The left adrenal nodule measures approximately 1.0 x 0.4 cm. The difference in size is likely due to different imaging modalities. There appears to be loss of signal on out of phase imaging (series 802/32), compared to in phase imaging (series 801/32), suggestive of a lipid rich adrenal adenoma.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Postsurgical changes from abdominal colectomy with right lower quadrant end ileostomy.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
The left adrenal nodule measures approximately 1.0 x 0.4 cm. Subtle loss of signal on out of phase imaging is suggestive of a lipid rich adrenal adenoma. However, its small size limits characterization and a follow-up CT in 6 months is suggested.
