24-year-old female patient with FNH. Surveillance imaging. ABDOMEN:LIVER, BILIARY TRACT: Again seen are multiple T2 hyperintense lesions throughout the liver parenchyma, similar compared to prior.In the posterior right hepatic dome there is a T2 hyperintense and arterially enhancing lesion that measures 1.9 x 1.2 cm on arterial enhanced images (series 1002 image 297), unchanged when measured similarly. This lesion does not retain contrast on delayed hepatobiliary phase images and demonstrates trace washout on hepatic phase imaging.There is a lesion in the anterior left lobe of the liver that measures 1 cm and is dark on T1 and T2 and does not demonstrate enhancement and may represent a hemorrhagic cyst.Numerous additional high T2 and arterially enhancing lesions within the liver demonstrate retention of contrast on hepatobiliary phase imaging, compatible with focal nodular hyperplasia. These lesions appear similar compared to prior exam.No intra or extra hepatic biliary ductal dilatation.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: Peribronchovascular soft tissue thickening in the right lower lobe noted and optimally evaluated on prior CTs of the chest.
1.Lesion within the posterior right hepatic dome with atypical imaging characteristics may represent an atypical FNH or an adenoma.2.Numerous additional lesions throughout the liver parenchyma with imaging features compatible with FNH appear similar compared to prior.
