Additional findings on PET/CT (True-Positive) compared to CECT (False-Negative): A 45-year-old female experienced jaundice with abdominal pain for 2 months. Serum CA19-9 was elevated (926.7 U/ml). (A) PET/CT showed focal ¹⁸F-FDG uptake in the head of the pancreas (SUVmax 3.6). (B) CECT only showed obstruction, calcification, and the atrophy of pancreatic parenchyma subsequent to chronic pancreatitis. Patient then underwent pancreaticoduodenectomy, and histopathology revealed moderately-differentiated pancreatic ductal adenocarcinoma complicated with chronic pancreatitis.
