Abstract
We report the clinical and multimodal PET/CT manifestations in a patient with behavioral variant frontotemporal dementia and parkinsonism. The 18 F-FDG PET scan revealed hypometabolism in the left supratentorial cortex. The 18 F-fluorodopa PET scan demonstrated decreased uptake in the bilateral striatum, most prominent in the head of caudate nucleus. The 18 F-florbetapir PET scan indicated an absence of β-amyloid deposition, whereas the 18 F-flortaucipir PET scan showed uptake in the left hemisphere neocortex. The clinical presentation and asymmetric neuroimaging features supported the underlying frontotemporal lobar degeneration-tau pathology.
