Mesenteric carcinoid tumor cryoablation. a Preoperative abdominal CT image demonstrating a calcified mesenteric mass surrounded by bowel loops, ventral hernia, and an anterior window to access the mass percutaneously. b Postoperative abdominal CT image demonstrating hypodensity in the region of the mass without evidence of ablation to surrounding bowel and contrast used for hydrodissection. c One-month follow-up CT confirming >90% tumor coverage with minimal rim enhancement. d Preoperative abdominal CT image with measurements of the lesion. e Four-month follow-up CT with measurements revealing a 20–25% decrease in tumor size.
