99mTc-TRODAT-1, as a tropane-derived compound with highly selective binding to the dopamine transporter, has been extensively used as an in vivo biomarker to evaluate parkinsonism. There have been few reports indicating various etiologies about extrastriatal findings on the 99mTc-TRODAT-1 SPECT. We herein present an interesting case about the incidental discovery of brain lymphoma with increasing uptake of 99mTc-TRODAT-1.
