A 54-year-old woman underwent a Whipple procedure for pancreatic carcinoma and developed a solitary right liver metastasis 3 months after surgery (arrow, a ). The tumor was treated with microwave ablation and immediate postablation scan ( b ) demonstrated a minimum 1 cm margin. At 1-month follow-up imaging, the ablation zone ( c , arrow) contracted without evidence of residual tumor. This approach allowed the patient to remain off chemotherapy until developing a greater metastatic burden.
