Early- and late-phase 18F-FP-CIT PET images in vascular parkinsonism due to midbrain infarct

The term vascular parkinsonism (VP) has remained debated because the definition is unclear and the mechanisms seem to be heterogeneous . It is suggested that the damage to nigrostriatal and subcortico-cortical pathways may lead to parkinsonism . Dopamine transporter imagings in VP seem to be inconsistent. We introduce a VP patient showing the abnormal dopaminergic activity of the ipsilateral striatum after focal midbrain infarction, which was rarely reported.
A 71-year-old, right-handed woman with a previous history of hypertension visited our clinic for both hand tremor and bradykinesia. She reported that the right hand tremor occurred 4 years ago, and the left hand tremor and bradykinesia, 1 year ago. She denied acute onset of those symptoms. She told us that her hand tremor occurred while writing, using a spoon, and the rest. Constipation occurred 1 year ago, but there were no other non-motor symptoms such as REM sleep behavior disorder (RBD) and urinary problem....
