Features worrisome for recurrence. (a) Pre-op CT, a soft tissue mass (white arrow) is seen surrounding the SMA; (b) immediately post-op, hazy amorphous soft tissue (white arrow) is seen surrounding the SMA. There is some enhancement of the ablation bed; (c) 2 months post-op, there is new narrowing of the SMA (black arrow) with enlarging soft tissue at the postablation zone. Its anterior borders cannot be separated from adjacent bowel (white arrow). Increased volume and new narrowing of a vessel are suggestive of recurrence.
