CT
What is the cause of this heterogeneous appearance of the liver?
Probable liver involvement in hereditary haemorrhagic telangiectasia (HHT).
Arterial phase CT scans demonstrate heterogeneous enhancement of the liver, more evident in the right lobe; portal phase images show a normal liver appearance.
There is also prominence of the hepatic artery and its intrahepatic branches, as well as early filling of a dilated left hepatic vein.
