Bilateral parkinsonism in a patient with infarcts involving the unilateral basal ganglia
We describe a 61-year-old woman with bilateral parkinsonism caused by unilateral infarction limited to the territory of the lenticulostriate arteries. Although dopamine transporter imaging with single-photon emission computed tomography (DaTSPECT) demonstrated reduced putaminal tracer binding concor...

Summary: | We describe a 61-year-old woman with bilateral parkinsonism caused by unilateral infarction limited to the territory of the lenticulostriate arteries. Although dopamine transporter imaging with single-photon emission computed tomography (DaTSPECT) demonstrated reduced putaminal tracer binding concordant with the size and location of the vascular lesion, the specific binding ratio was within the normal range. Five months after onset, the patient was free from parkinsonism without the use of any antiparkinsonian agents. When patients show bilateral parkinsonism, it is important to consider infarction of the lenticulostriate arteries. Additionally, DaTSPECT might be useful for predicting the prognosis of parkinsonism caused by infarction.
•We present a case with bilateral parkinsonism caused by unilateral striatum infarcts.•DaTSPECT showed right putamen hypoactivity.•However, specific binding ratio was within the normal range.•Her symptoms fully recovered without antiparkinsonian agents.•DaTSPECT may be useful for us to predict a patient's prognosis. |
