Abstract

A 27-year-old woman underwent 68 Ga-pentixafor PET/CT for primary aldosteronism localization and characterization. No functional adrenal nodules were detected by 68 Ga-pentixafor PET/CT, whereas a hypodense nodule with focal pentixafor uptake was incidentally discovered in the head of pancreas. Retrospective analysis of contrast-enhanced CT scan revealed a subtly enhancing nodule devoid of calcification in the pancreatic head. Pancreatic cancer cannot be excluded. 18 F-FDG PET/CT was suggested, and the scan showed an FDG-avid lesion in the same region. Needle biopsy was performed, and the pathological result is solid pseudopapillary tumor, a rare pancreatic tumor of low malignant potential.
