Abstract:
Hepatic pseudomasses have been described on both non-contrast and contrast-enhanced computed tomography (CT) scans, as well as on scans obtained by CT-arteriography and CT-portography. The authors describe a hepatic pseudomass that appeared in CT scans after direct injection of contrast material into the portal vein through an indwelling catheter.
