Pituitary macroadenoma on 99mTc-TRODAT-1 brain SPECT.
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.
