Colorectal cancer is the third most common cancer worldwide, and liver metastases are highly prevalent among patients with the condition. Many patients are not candidates for radical surgery due to the timing of diagnosis; therefore, local treatments, such as ablation, have received considerable attention among clinicians and researchers. Here, we report the case of a patient who was treated successfully using ultrasound-positron emission tomography/computed tomography (US-PET/CT) fusion image-guided microwave ablation (MWA) for colorectal liver metastases (CRLM). This technique combines the individual advantages of ultrasound and PET/CT and minimizes the effects of their limitations. We conclude that image-guided ablation therapy is an important approach to treating CRLM. Using US-PET/CT fusion images may represent a new image-guidance method for ablation therapy of CRLM.
