Patchy, mosaic enhancement of liver parenchyma with periportal edema due to hepatic congestion. Hepatic veins are not visible.

Case Discussion

Elevated central venous pressure causes hepatic congestion and decreases hepatic blood flow. Increased hepatic venous pressure results in sinusoidal congestion, dilatation of fenestrae and exudation of protein and fluid into the space of Disse. This accumulation of exudate as well as decreased hepatic blood flow promote liver injury.
