A 55-year-old man with pancreatic cancer metastatic to the liver underwent percutaneous radiofrequency ablation (RFA) of the liver deposits. The liver harboured four metastatic foci, the largest of which was located at the posterior part of the right lobe just below the diaphragm (figure 1A). Due to the difficult anatomic location, transpulmonary approach was chosen for RFA and CT guidance was needed rather than ultrasound.

Under CT guidance an Accu 2i probe (Acculis Microwave Tissue Ablation System, AngioDynamics, Latham, New York, USA) was advanced into the four liver metastases. Ablation was performed at 140W at multiple sites for a total of 50 min. Small subcapsular haematoma …
