Characterization of mass. a Coronal first-pass perfusion MR image in a patient who presented with chest pain and IVC mass on echocardiography shows a mass that demonstrates contrast enhancement similar to the liver parenchyma. The mass also showed similar signal to liver in all other MRI sequences (not shown here). b Coronal FDG-PET/CT image shows no uptake in the lesion, indicating it is a benign process. This was proven to be a rare case of aberrant liver, which extended into the IVC
