Especially remarkable is that serum PTH was abnormally high in this patient, whereas 68Ga-DOTATATE and 18F-FDG PET/CT parathyroid imaging showed no abnormality in the parathyroid region, probably due to the small size of the lesion at present; adenomas of the parathyroid should be watched carefully over her lifetime. The gene discussed is PTH; the disease is adenoma.
