The angiographic features of intrahepatic abscesses have not been clearly defined. However, inflammatory lesions of the right upper quadrant can be accurately localized by selective angiography. Three cases of 18 mth, 9 and 16 yr of age are reported, in whom selective hepatic angiography revealed single or multiple liver abscesses. The angiographic findings in the single liver abscess include convex displacement and stretching and flattening of intrahepatic arteries, with a marginal rim of increased opacification. The changes are secondary to the growing space occupying lesion, which is avascular at its center. In multiple small liver abscesses, angiography reveals a rich arterial vascularization and the hepatogram is grossly abnormal with irregular nonopacified areas within regions of marked staining.
