Pseudolesions of the liver can be mistaken for primary hepatic tumors or metastases and are due to hemodynamic alterations which affect hepatic enhancement. There is no associated mass effect.

They can be classified into:

portal vein obstruction with consequent increased arterial flow and transient early enhancement
arterioportal shunts
arteriovenous shunts
third inflow from adjacent veins that enter the liver and anastomose with portal vein branches
pseudolesions due to focal compression of the liver by structures such as ribs or diaphragm which reduce portal venous flow

The characteristic locations are:

around the gallbladder fossa
the anteromedial aspect of the left lobe
the posterior region of the medial segment of the left lobe, anterior to the right portal vein

Hepatic pseudolesions may also result from focal parenchymal steatosis or sparing, focal hypertrophy or imaging pitfalls ³.
