For two patients with partial Budd-Chiari syndrome secondary to
hepatocellular carcinoma, dynamic CT was evaluated. The obstructed hepatic
veins were both the middle and left hepatic veins in Case 1 and the right
hepatic vein in Case 2. The area affected by obstructed hepatic vein(s) was
seen as low density on both unenhanced and contrast enhanced CT in Case 1
and as high density on enhanced CT in Case 2. The border of attenuation
differences caused by the obstruction of the middle (Case 1) or right (Case
2) hepatic vein was intersegmental planes of the anterior segment of the
right lobe, and that caused by the obstruction of the left hepatic vein was
the intersegmental plane of the medial third of the left lateral segment.
Once intersegmental attenuation difference is recognized on CT, partial
Budd-Chiari syndrome should be considered.
