35-year-old with history of melanoma with focal nodular hyperplasia on prior exam. Evaluate for interval change. ABDOMEN:LIVER, BILIARY TRACT: Redemonstration of the patient's known left lobe mass which measures 6.3 x 5.6 cm (series 9 image 65), previously 6.5 x 6.0 cm. There is avid early arterial enhancement with delayed filling of a central scar. The lesion becomes isointense to the background liver and have increased in density on the delayed hepatobiliary phase images. Findings are again compatible with focal nodular hyperplasia.There is an additional lesion in segment 4 which has similar imaging characteristics and is also not significantly changed in size measuring 1.5 x 1.1 cm (series 9 image 62), previously 1.4 x 1.0 cm.There are additional smaller foci of arterial enhancement (series 9 image 65 and series 9 image 69) that appear similar to prior and also likely represent additional small foci of focal nodular hyperplasia. No new suspicious lesions.The liver parenchyma is normal in signal and morphology. The hepatic veins, hepatic arteries, portal veins are patent.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.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.
1.Multiple foci of focal nodular hyperplasia which are not significantly changed from prior. No evidence of metastatic disease.
