Percutaneous radiofrequency ablation of a lung metastasis: delayed cavitation with no infection.

A 64-year-old man presented with a lung metastasis of the lower left lobe. After partial response with chemotherapy, a thoracotomy was performed that did not allow a wedge resection, and lobectomy was contraindicated by the patient's ventilatory function. Radiofrequency ablation of this lung metastasis was thus performed, followed by a delayed cavitation with no infection, which, to our knowledge, has not yet been described.
