T1MRI image with hypo-intense lesion in the right hepatic

lobe

T2MRI image showed small hyper-intense central
scar.

disappearance of enhancement after one minute
from injection.



homogenously hyper-intense enhancement of
the mass.
important sign=no evidence of surounding capsule.(this important to differentiate it from hepato-cellular carcinoma with central scar.

hepatic arterial phase

M=mass

open arrow=central scar

arrow=left hepatic artery

hepatic arterial phase at a higher level shows

enlarged left heptic vein denoting arterio-venous

shunt.

redistribution (portal)phase the mass becomes hypo-attenuated

relatively to hepatic parenchyma.
