Thinking outside the abdominal box: safe use of the epipericardial fat pad window for percutaneous radiofrequency ablation of hepatic dome tumors.

Percutaneous imaging-guided tumor ablation is being increasingly performed for local disease control in a variety of primary and secondary neoplasms. Herein, the authors detail their experience with four patients in whom the epipericardial fat pad was traversed to access tumors within the hepatic dome for radiofrequency ablation. The procedure was technically successful in all patients, and the use of this novel window helped avoid crossing the pleura.
