Incidental 18F-Flortaucipir Uptake in Pituitary Macroadenoma
A 73-year-old woman with over 2 years of progressive memory decline underwent amyloid PET/CT (18F-florbetaben) and tau PET/CT (18F-flortaucipir) imaging for suspected Alzheimer disease (AD). This series of examinations confirmed the diagnosis of AD. Unexpectedly, a pituitary macroadenoma with significant 18F-flortaucipir uptake was revealed, which might represent another instance of off-target binding.
