Factors Contributing to Cavitation after CT-guided Percutaneous Radiofrequency Ablation for Lung Tumors

In our study, cavitation occurred at a frequency of 14% at 1.5 months ± 0.8 after RFA ablation, but the majority of patients were asymptomatic. Cavitation seems to occur more frequently in patients with a lesion near the chest wall, lung cancer as the primary lesion, and in those with pulmonary emphysema at baseline before the lung RFA.
