Figure 9a — Suspected recurrent pancreatic adenocarcinoma in a 52-year-old man with a history of Whipple resection. (a) Axial contrast-enhanced multidetector CT image shows a soft-tissue abnormality in the surgical bed (arrow) that was not considered to be a nondistended jejunal segment. Because a borderline increase in tumor marker CA 19-9 was also present, this finding is suspicious for tumor recurrence. (b) Fused PET/CT image shows no obvious increased FDG uptake in the surgical bed. At follow-up contrast-enhanced CT, the soft-tissue abnormality remained stable, ruling out tumor recurrence. This case highlights the role of PET/CT in the follow-up of patients with equivocal CT findings who underwent surgery for pancreatic adenocarcinoma.
