Figure 2

Complete response after SBRT for a liver metastasis over successive follow-ups. Before treatment (a); 2 months later (b), we observe changes of the initial phase: target-shaped lesion surrounded by a peripheral enhancement and located in a hypodense area with well delineated demarcation between irradiated and normal liver; CT slices performed at portal phase at 5 months (c); 9 months (d); 12 months (e); and 24 months later (f) show that the center is better circumscribed by a thin rim enhancement, the hypodense area progressively shrank and became hyperdense.
