(A) An exophytic rounded cystic lesion characterized by (B) an avid contrast enhancement along septa at CEUS examination. (C,D) The same lesion showed no enhancement at CECT (arrowhead); (D) a ring of fat-stranding due to persisting edema persists at CECT performed 1 month after treatment (arrowhead).

3. Fig. 2
Two different lesions observed and treated in the same patient (top and bottom panels). Top panel: (A) antenna entrance site; (B) lesion (asterisk); (C) this lesion appeared as completely necrotized without contrast enhancement at CECT performed 1 month after MWA treatment. Bottom panel: (D,E) the larger lesion appeared necrotized with a “halo” of fat-stranding 1 month after MWA treatment (arrowhead, E); (F) the “halo” progressively disappeared at CECT 24 months after treatment: a volume reduction of the ablated lesion was identified (arrowhead).

4. Fig. 3
(A,B) A small rounded exophytic lesion on axial (arrowhead, A) and coronal (arrowhead, B) reformatted CECT images before MWA treatment. (C) The same lesion during the MWA session: the dotted line shows the planned antenna track, the green circle the antenna entrance site and the violet oval the planned ablation area (diameter 3.7 cm). (D) The asterisk shows the ablated area on CECT performed immediately after MWA treatment; in particular some air bubbles of vaporization near the ablated site may be observed. (E,F) CECT performed 1 month (arrow, E) and 24 months (arrow, F) after MWA treatment showing absence of residue/recurrence.
