Abstract:
Dopamine transporter (DAT) radiopharmaceuticals are capable of binding to the DAT with high selectivity, especially in the corpora striata, and have been widely used to evaluate parkinsonian disorder. However, only a few reports have mentioned about the extrastriatal pathologic DAT uptake. Herein we present an interesting case about the incidental discovery of pituitary macroadenoma with intense uptake of 99mTc-TRODAT-1.
