From: Repeat thermal ablation for local progression of lung tumours: how safe and efficacious is it?

Figure 4. 57-year-old female with right upper lobe squamous cell carcinoma. A, B: Repeat microwave ablation, 2 overlapping ablation cycles; C: axial CT 24 h post re-ablation shows circumferential ground-glass opacity of at least 1 cm; D: axial CT 6 months post re-ablation shows significant shrinking of ablation site with central cavitation
