Surgical resection plus biotherapy/chemotherapy improves survival of hepatic metastatic melanoma

Table 2 The characteristics on imaging of the hepatic metastatic melanoma

Case	Tumor location	Tumor size	B-ultrasound	Computed tomography
1	Right liver	4.3 cm × 3.3 cm × 3.1 cm	NA	NA
2	Multiple	5 mm-12 cm	Low echo	Low density
3	Multiple		NA	Low density
4	Left liver	2.4 cm × 2.5 cm	Low echo, with partially peripheral dense echo	NA
5	Right liver	6.4 cm × 5.0 cm	Low echo, with peripheral low-echo areola, and a bit of strip blood flow inside	Low density
6	Multiple	5 mm-3 cm	Low echo, with peripheral low echo areola	Low density, with higher density peripherally
7	Left liver	2.5 cm × 2.1 cm	Mid-dense echo	Low density, with nodular enhancement
8	Multiple	5 mm-2.6 cm	Low echo	NA
9	Right liver	10 cm × 8 cm	No echo, with septum, and hyperechoic lesion	Cystic mass, with mild enhancement
