Abstract
We reported a 91-year-old man who was suspected of having parkinsonism, and brain 99m Tc-TRODAT-1 scan revealed an extrastriatal uptake in the left side of brainstem, which was correlated to a previously hemorrhagic lesion with hemosiderin deposition. Macrophage or microglia might accumulate in the previous hemorrhagic lesion to phagocytize hemosiderin. We assumed that the 99m Tc-TRODAT-1 uptake in the hemosiderin deposition might be partially mediated by macrophage expressing dopamine transporter.
