case_images: Whole body 18F-FDG PET/CT scan of a 70-year-old female with PPL. (A) MIP demonstrated a hypermetabolic lesion in the superior abdominal. (B,C) A 9.5 x 8.3 x 7.1 cm high FDG-avid irregular occupying at the head of the pancreas with a SUVmax 22.4 (red arrow). (D, E) Peripancreatic hypermetabolic enlarged lymph nodes (red arrow). (F, G) Suspicious mild hypermetabolic retroperitoneal lymph node with (red arrow). PPL, primary pancreatic lymphoma; 18F-FDG PET/CT, 18F-fluorodeoxyglucose positron emission tomography/computed tomography; MIP, maximum intensity projection; SUVmax, maximal standardized uptake value.

case_images: The maximum intensity projection (MIP) of the 18F-FDG PET/CT divulged a hypermetabolic lesion within the upper abdomen (Figure 1A). A 9.5 x 8.3 x 7.1 cm irregular lesion situated at the pancreatic head exhibited noteworthy FDG uptake, characterized by a maximal standardized uptake value (SUVmax) of 22.4 (Figures 1B-E). Mild to moderately FDG-avid peripancreatic lymph nodes, displaying indistinct boundaries with the pancreatic mass (Figures 1B-E). Additionally, mildly hypermetabolic retroperitoneal lymph nodes were detected (Figures 1F, G).

case_images: Whole body 18F-FDG PET/CT scan of a 31-year-old male with PPL. (A) MIP showed a hypermetabolic mass in the superior abdominal and peripheral lesions. And mild hypermetabolic of FDG were observed in the thoracic spine. (B, C) A 5.5 x 5.4 cm high FDG-avid mass at the head and neck of the pancreas with SUVmax 22.0 (red arrow). (D,E) Hypermetabolic lymph nodes in the posterior of pancreatic region (red arrow). (F,G) Left clavicular region lymph node with mild FDG hypermetabolism (red arrow). (H, I) Suspicious mild hypermetabolism within the left internal mammary lymph nodes (red arrow). PPL, primary pancreatic lymphoma; 18F-FDG PET/CT, 18F-fluorodeoxyglucose positron emission tomography/computed tomography; MIP, maximum intensity projection; SUVmax, maximal standardized uptake value; CT, computed tomography.

case_images: Subsequent 18F-FDG PET/CT illustrated a hypermetabolic lesion situated in the upper abdomen, with peripheral subsidiary lesions evident in the maximum intensity projection (MIP) (Figure 2A). Notably, the thoracic spine also exhibited mild hypermetabolism (Figure 2A). 18F-FDG PET/CT delineated a conspicuously intense hypermetabolic lesion (SUVmax 22.0) situated at the head and neck of the pancreas. Concurrently, hypermetabolic lymph nodes in the posterior pancreatic region were observed (Figures 2B-E). Additionally, mild hypermetabolic (SUVmax 2.3) lymph nodes were found in left clavicular region and left internal mammary (Figures 2F-I).
