Solid pseudo-papillary tumor (SPT) is a rare pancreatic neoplasm with low malignant potential, which tends to occur predominantly in younger females. Only a few cases of SPT seen on F-18 FDG PET scan have been reported, and the findings are not fully evaluated. A 33 year-old woman underwent F-18 FDG PET/CT study for staging of renal cell carcinoma. She was diagnosed with SPT of the pancreas 6 years ago, and has not had any treatment so far. Recent PET/CT showed marked F-18 FDG uptake in the peripheral solid portion and relatively less F-18 FDG uptake to the central calcified portion of SPT. We report one case of SPT of the pancreas on F-18 FDG PET/CT.
