Overview
The ultrasonographic features of hepatocellular adenoma are non specific and may appear as hyper-, iso-, or hypo-echoic. It can show a hyper echoic mass. The color doppler ultrasound shows intratumoral veins associated with peritumoral veins and arteries. The contrast enhanced ultrasound is hypervascular in the arterial phase and shows centripetal filling in the portal venous and delayed phases.
Echocardiography/Ultrasound
- The ultrasonographic features of hepatocellular adenoma are non specific and may appear as hyper-, iso-, or hypo-echoic.[1]
- The classic appearance of hepatocellular adenoma is a well demarcated hyper-echoic mass.
- Central necrosis and hemorrhage gives rise to heterogeneous echogenecity that can resemble focal nodular hyperplasia.[2]
- The contrast enhanced ultrasound of hepatocellular adenoma is hypervascular in the arterial phase and shows centripetal filling in the portal venous and delayed phases.
- The color doppler ultrasound features of hepatocellular adenoma include:
