Striatal 123 I-2β-carbomethoxy-3b-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane single-photon emission computed tomography demonstrates nigral degeneration in the early stage of behavioural variant frontotemporal dementia: an autopsy case with frontotemporal lobar degeneration with trans-activation response DNA protein 43 type B

Behavioral Variant Frontotemporal Dementia With the Dominantly Affected Caudate Nucleus in 18 F-FP-CIT PET/CT

ABSTRACT

Frontotemporal dementia is a clinical syndrome that is characterized by a progressive deterioration in behavior, personality, and/or language, with relative preservation of memory, and its phenotype and molecular basis are heterogeneous. We present a case of a 62-year-old female patient who underwent 18 F-FDG PET/CT and 18 F-FP-CIT PET/CT for differential diagnosis of psychiatric disease and types of dementia. 18 F-FDG PET/CT image showed a compatible finding for frontotemporal dementia, and 18 F-FP-CIT PET/CT image showed dominantly decreased dopamine transporter activity in the bilateral caudate nucleus.
