A 50-mm mass in the S8 and a 15-mm mass in the S7-8 were described as a high-, iso-, and low-density lesion and a high-density lesion, respectively, at the early phase (a) and as low-density lesions at the delayed phase (b) on dynamic CT.

Dynamic contrast-enhanced CT scan showed a partially hypervascular tumor with necrotic area in the S8 and a hypervascular tumor in the S7-8 (fig. 1) and 10-mm hypervascular tumors in the other segments (S6 and S4) on August, 2010.
The mass in the S8 decreased to 30 mm and was described as a low-density lesion on CTA. The mass in the S8-7 diminished to 10 mm and was described as a high-density lesion on CTA.

The 50-mm mass in the S8 decreased to 30 mm and became completely necrotic on CT arteriography (CTA) (fig. 2) on September, 2010. The 15-mm mass in the S8-7 diminished to 10 mm and was described as an enhanced lesion on CTA (fig. 2).
Tumor stain and occlusion were absent in the A8 (a, b) on the right anterior arteriography of the liver. There was tumor stain in the A7 (c) on the selective right posterior superior arteriography of the liver.

Hepatic angiography disclosed no tumor stain and occlusion in the right anterior superior arteries (A8) (fig. 3a, b). Tumor stains were noted in the A7 (the above mass in the S8-7) (fig. 3c), A6, and A4.
