Figure 4

(a) and (b) Preoperative CT scans in axial and coronal planes showing soft tissue mass (white arrow) in the pancreatic uncinate process extending into the small bowel mesentery with vascular encasement. (c) and (d) Immediate postoperative CT scans demonstrating a slight fluid collection in postablative zone (white arrow) with ill-defined margins and internal gas compatible with liquefaction from ablation procedure. (e) and (f) Two-month follow-up scans demonstrating a smaller ablation zone (white arrow) with increased enhancement and less gas suggesting no recurrent disease.
