Classic imaging appearance of a LI-RADS 5 lesion (definitely hepatocellular carcinoma). This lesion was not present on an MRI performed ~9 months earlier.
- T2 fat sat: mild hyperintensity of the lesion
- precontrast phase: mild hypointensity of a peripheral ovoid lesion in the right hepatic lobe
- arterial phase: intense enhancement of the 2.6 cm lesion (late arterial phase)
- portal venous phase: decreased enhancement of the lesion on the portal venous phase with a faint capsule remaining; the lesion now appears to be isointense to background liver
