77-year-old male with left adrenal mass which is hypermetabolic on recent PET scan. ABDOMEN:LIVER, BILIARY TRACT: 1.8 x 1.9 cm cystic lesion in segment 4a/b with thin internal septations and no significant enhancement, most likely a benign complex cyst (series 801/21). Additional scattered subcentimeter T2 hyperintense lesions are too small to characterize but likely benign cysts.SPLEEN: Small splenule noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: 3.3 x 3 cm left adrenal mass demonstrating loss of signal on opposed phase images and most compatible with benign adenoma (series 801/22).KIDNEYS, URETERS: Subcentimeter T2 hyperintense lesions in both kidneys are too small to characterize but likely benign 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.
1. Left adrenal mass is most compatible with a benign adenoma, but a single follow-up in 12 months is recommended given its size.2. No evidence of metastatic disease in the abdomen.
