65-year-old woman with history of alcoholic cirrhosis and liver lesion seen on 2015 MRI. ABDOMEN:LIVER, BILIARY TRACT: Liver appears cirrhotic in signal and morphology. In segment 4A (20/371), there is a 9 x 8 mm area of washout which appears similar in size to prior examination, previously 9 x 7 mm. This area does not demonstrate early arterial enhancement, abnormal T2 signal, or abnormal diffusion signal. This region does contain fat as evidenced by signal dropout on opposed phase imaging.Additionally, there is a new geographic focus of arterial enhancement in segment 4A (20/166). This area does not washout on delayed phase imaging and is isointense to liver on T2 without restricted diffusion.The portal vein is patent.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Subcentimeter right renal cysts 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.
1.Stable nonspecific segment 4A lesion.2.New arterially enhancing segment 4A lesion which is also nonspecific but not characteristic of HCC and can be followed on subsequent imaging.
