Structural and Functional Imaging of the Patient's Brain. Brain MRI nonenhanced T2 FLAIR images acquired 4 months (A) and 12 months (B) after initial symptom showed marked striatal hyperintensity and striatal atrophy, respectively, and FP-CIT PET scan showed a decrease in DAT binding in the bilateral striatum (C). Abbreviations: [18F] N-(3-fluoropropyl)-2beta-carbomethoxy-3beta-(4-iodophenyl) nortropane (FP-CIT) positron emission tomography (PET); DAT, Dopamine Active Transporter; FLAIR, Fluid Attenuated Inversion Recovery; MRI, Magnetic Resonance Imaging.

On the brain MRI images acquired at 12 months after the symptom onset, marked bilateral striatal atrophy was observed (Figure 1B). T2-hyperintensities were present in the bilateral caudate nucleus and anterior putamen (Figure 1A). On the [18F] N-(3-fluoropropyl)-2beta-carbomethoxy-3beta-(4-iodophenyl) nortropane (FP-CIT) positron emission tomography (PET) scan, decreased uptake in the bilateral striatum, especially in the caudate nucleus was obtained (Figure 1C).
