Clinical Application of CT-Guided Percutaneous Microwave Ablation for the Treatment of Lung Metastasis from Colorectal Cancer

Figure 1

A 73-year-old man with lung metastasis from colorectal carcinoma in left upper lobe with an axial diameter of 2.3 cm (a). Ablation was performed after accurate insertion of MWA probe into the focus of tumor (b). The immediate postoperative CT scan showed that the lesion enlarged slightly with ill-defined and irregular margin (c). The lesion was shrunk gradually and replaced by fibrous tissue during 1 (d), 3 (e), and 6 (f) months follow-up.
