Case 185: Hepatic Congestion

Diagnostic Category:

Clinical Presentation:

35 year old woman: status post mitral valve repair due to endocarditis.

CT: Typical mosaic perfusion pattern

Imaging Findings:

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.
