Aside from RF ablation ( Radiofrequency ablation ) of the liver, we have performed successfully RF ablation of lesions in the adrenal gland, bone, lung (primary and metastatic disease) and kidneys. The adrenal mass was a metastatic lesion from a primary lung malignancy. The main indication for RF ablation of metastatic bone disease is for control of pain. Some of our lung cases and kidneys are surgically resectable. However, the patients opted for RF ablation due to co-morbidities or refused to undergo surgery.
