A case of hemiparkinsonism with posterior cerebral artery giant aneurysm performing a FP-CIT PET study: Is it co-existing aneurysm or cause of hemiparkinsonism?

초록

Rarely, it was reported the large aneurysm could be revealed a hemiparkinsonism in some case reports. We report the case of a patient who developed predominantly right-sided parkinsonism with giant aneurysm on posterior cerebral artery (PCA). The hemiparkinsonism by PCA aneurysm was not reported, from what we know. And, this is the first case that performing FP-CIT PET on hemiparkinsonism with giant aneurysm. Initially, we probably thought the parkinsonism was a result of giant aneurysm of the PCA, secondary to midbrain compression by aneurysm. However, it could not be excluded the idiopathic parkinsonian disease (IPD) by the result of FP-CIT PET. The levodopa was administrated and her gait disturbance and bradykinesia was improved. © 2018
