Non-small-cell lung carcinoma (NSCLC) located in the right lower lobe, adjacent to a segmental bronchus (A). RFA was successfully performed (B). The 1-month CT control demonstrated a large area of cavitation including the entire nodule, with no significant contrast enhancement (C,D); the findings were considered indicative of complete response. The 6- and 12-month CT examinations (E,F) demonstrated the progressive reduction in size of the cavitation with formation of a fibrotic band, corresponding to a complete response to treatment
