A 37×32 mm arterially hypervascular mass with a central non-enhanced scar is present at segment V of the liver that becomes isodense with surrounding hepatic parenchyma on the portal venous and delayed phases.
Case Discussion
Features on CT scan are most consistent with focal nodular hyperplasia which is the second most common benign liver lesion (most common is hemangioma). On post-contrast images, FNH demonstrates bright homogeneous arterial contrast enhancement except for the central scar which remains hypoattenuating.
