Ultrasound

• The ultrasonographic features of hepatocellular adenoma are non specific and may appear as hyper-, iso-, or hypo echoic.
• The classic appearance of hepatocellular adenoma is a well demarcated hyper echoic mass, whereas, central necrosis and hemorrhage gives rise to heterogeneous echogenecity that can resemble focal nodular hyperplasia.
• The color doppler ultrasound features of hepatocellular adenoma include; intratumoral veins associated with peritumoral veins and arteries.
• The contrast enhanced ultrasound of hepatocellular adenoma is hypervascular in arterial phase and shows centripetal filling in portal venous and delayed phases.
