25 years, Female, Reason: dedicated liver MRI, interested in the liver mass (Focal Nodular Hyperplasia vs Ewing's sarcoma) History: Recent scans showing liver mass, biopsy in 2012 FNH. Chest mass found on CXR/CTs, plan for surgery 3/5. Eval liver mass prior to surgery. ABDOMEN:LUNG BASES: No significant abnormality notedLIVER, BILIARY TRACT: Large segment IVb lesion shows mild T2 hyperintensity, homogenous arterial enhancement which mildly persists on delayed phases including hepatobiliary phase, and measures 4.0 x 4.5 cm (901/197), previously 2.6 x 2.6 cm. These signal characteristics are compatible with focal nodular hyperplasia.Additional lesions are also increased in size including a segment 3 lesion which measures 2.3 x 1.6 cm (901/222), previously 1.4 x 0.8 cm and a segment 6/7 lesion which measures 2.3 x 1.6 cm, previously 1.6 x 1.5 cm. These lesions show arterial enhancement as well as delayed enhancement on hepatobiliary phase, likely representing focal nodular hyperplasia. Additional smaller lesions have similar signal characteristics.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Left hepatic lesion is seen previously is no longer visualized, possibly artifact on the prior exam.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.
Multiple hepatic lesions have signal characteristics compatible with focal nodular hyperplasia.
