Case 184: Hepatic Congestion
59 year old man with congestive heart failure.
CT: Typical marble perfusion pattern
CT demonstrates massively dilated hepatic veins and delayed opacification of the hepatic parenchyma due to venous congestion in the portal venous phase, giving the appearance of "marble" perfusion. The mechanism of this enhancement pattern is identical to that of mosaic perfusion, but this portal venous contrast phase is slightly later than a mosaic pattern.
