Incidental liver mass seen on outside hospital CT. The study is suboptimal due to patient motion.ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, contour and size measuring 18 cm in craniocaudal dimension. No intrahepatic or extrahepatic biliary ductal dilatation. The liver orientation is different from the outside hospital comparison CT. The right hepatic dome peripheral lesion appears to be at a different level relative to the gallbladder but this is felt to be likely due to positioning and liver orientation. Definite characterization of the lesion is limited due to extensive respiratory motion. The lesion demonstrates mild homogeneous T2 weighted hyperintensity, not the typical appearance of a hemangioma. On dynamic postcontrast imaging the lesion demonstrates arterial enhancement which persists on the portal venous and delayed imaging. The 1 hour delayed hepatobiliary phase demonstrates no retention of contrast, which would be expected in a typical FNH. The lesion demonstrates nonspecific mild restricted diffusion.SPLEEN: Mild splenomegaly measuring 14 cm in craniocaudal dimension.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.
Limited study due to patient motion and respiration. The right hepatic dome lesion is difficult to see and definitively characterize. The features of the lesion are not that of a typical hemangioma or FNH. In the absence of a known hypervascular primary malignancy or risk factors for HCC the lesion is likely benign in etiology. However, given the suboptimal study, follow-up liver protocol CT (which will hopefully minimized motion) in 6 months is recommended. Borderline splenomegaly.
