A 63-year-old was found with bilateral lung metastases male 13 months after primary hepatoma carcinoma surgery, and after sorafenib treatment for three months, the lesions’ sizes were enlarged. A Nodules #1 (0.9 × 0.8 cm) and B Nodule #2 (1.4 × 1.1 cm) were observed in the left upper lung lobe. C Nodule #3 (1.4 × 1.1 cm) was observed in the right upper lung lobe. D Nodule #4 (1.3 × 1.1 cm) was observed in the right lower lung lobe. E, F MWA was performed on nodules #1 and #2 under CT guidance. G&H) MWA was performed on nodules #3 and #4 under CT guidance a month after MWA on nodules #1 and #2. I, J 2 months after the MWA session on nodules #1 and #2. K, L 1 month after the MWA session on nodules #3 and #4. M, N 6 months after the MWA session on nodules #1 and #2. O, P 5 months after the MWA session on nodules #3 and #4. Q, R 13 months after the MWA session on nodules #1 and #2, the lesions shrank to fibrous cords with no enhancement. S, T 12 months after the MWA session on nodules #3 and #4, the lesions shrank to fibrous cords with no enhancement. The efficacy was assessed to achieve complete ablation
