CT and MRI Findings of Hepatic Involvement in Rendu-Osler-Weber Disease
Figure 2
Axial CT scans obtained from different levels in the early arterial phase (a, d), late arterial phase (b, e) and late venous phase (c, f). During the arterial phases, millimetric hypervascular images disseminated throughout the hepatic parenchyma, referring to telangiectases that are no longer evident during the late venous phase are seen (white arrows). The early venous drainage with the simultaneous opacification of the dilated hepatic veins (black arrows) and the hepatic artery is evident during both arterial phases. Large confluent vascular masses are evident in the caudate lob (*). A strongly enhancing subcapsular area with irregular shape, relating to an area of transient hepatic parenchymal enhancement (arrowheads), is evident in the fourth segment. These changes are no longer evident during the late venous phase.
