Pulmonary hemorrhage after radioablation of liver metastases.

Percutaneous radiofrequency ablation of primary or secondary liver neoplasm is a minimally invasive new technique that is useful in high-risk surgical patients. We describe a case of pulmonary hemorrhage in a patient undergoing percutaneous radiofrequency ablation of liver metastases under general anesthesia. The patient subsequently had an uneventful recovery. We believe that radiofrequency energy caused injury to the diaphragm, pleura, and lung tissue.
