Female; 29 years old. Reason: evaluate liver mass. **FNH protocol** History: liver mass ABDOMEN:LIVER, BILIARY TRACT: Large mildly lobulated posterior right hepatic lobe mass measuring up to 10.6 x 9.7 cm (series 3/8), unchanged in size since prior CT. The lesion demonstrates nearly homogeneous T2 hyperintensity, early heterogeneous enhancement on arterial phase, homogeneous enhancement on portal venous phase, and very mild washout of contrast on 90 minute delayed phase. This lesion could be due to an adenoma, though the heterogeneous arterial enhancement and very mild washout 90 minutes would be atypical. As a result, malignancy cannot be excluded, and biopsy is recommended.No biliary ductal dilation.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.
Large right hepatic lobe lesion could be due to an adenoma, but malignancy cannot be excluded. As a result, biopsy is recommended. The lesion would be amenable to percutaneous biopsy.
