Abstract
Acromegaly is a rare disease frequently caused by a growth hormone-secreting pituitary adenoma (GHPA), and neuroimaging plays an important role in tumor localization, characterization, and surgical planning. A 57-year-old man underwent 68 Ga-DOTATOC PET/CT for an incidental pancreatic lesion. The PET revealed an increased radiotracer uptake and enlargement of the pituitary gland. The study was completed with 18 F-FDOPA and 18 F-FDG PET/MRI, which revealed a sellar lesion suggesting pituitary adenoma. Pathological examination of the resected tumor confirmed a GHPA.
