Cerebral vascular lesions are integral to the diagnosis of vascular parkinsonism (VP). The VP, also referred to as lower body parkinsonism, is frequently caused by subcortical white matter lesions, but lesions at any levels of the nigro-striato-thalamo-cortical pathway can also cause VP, thus giving rise to various symptoms other than gait disturbance. Previous dopamine transporter imaging studies using SPECT showed heterogeneous patterns suggesting diverse contributing lesions to VP. Here we present 3 cases of VP demonstrated by 18F-FP-CIT PET/CT, visualizing vascular lesions at different levels between the midbrain and motor cortex. Distinctive clinical manifestations of them recapitulate the pathogenesis of VP.
