Case 184: Hepatic Congestion

Diagnostic Category:

Clinical Presentation:

59 year old man with congestive heart failure.

CT: Typical marble perfusion pattern

Imaging Findings:

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.
