Case 185: Hepatic Congestion
35 year old woman: status post mitral valve repair due to endocarditis.
CT: Typical mosaic perfusion pattern
CT demonstrates arborized pattern of portal venous enhancement throughout the parenchyma, representing delayed opacification of the hepatic lobules due to cardiac insufficiency, resulting in venous congestion and mosaic perfusion pattern ("nutmeg" liver).
Compare to this case with hepatic congestion showing marble perfusion pattern.
