Fig. 8From: Imaging assessment after pancreaticoduodenectomy: reconstruction techniques—normal findings and complicationsLymphadenopathy vs. Tumor recurrence. CT challenge. Two different patients (a) 63-year-old female patient with persisting lymph node along 2-year follow-up. Six months, one- and two-years CT scans, respectively. Note the decreasing size of the node over time (big arrow). Clinical and biological markers level stable. (b) 65-year-old male patient along annual CT scan controls. An increasing lymph node is seen during the follow-up (large arrow). Note the rounded shape appearance and the short axis size greater than 10 mm (dotted circle) after three years from surgery. Tumor recurrence was proven by biopsy in patient BBack to article page
