case_images: Brain 18F-FDG PET images. Three-dimensional stereotactic surface projection images of the right lateral, left lateral, anterior, posterior, superior, inferior, right medial and left medial projections demonstrate hypometabolism in the frontal lobes, with greater hypometabolism toward the superior orbital gyrus and inferior opercular, triangular, and opercular gyri, with less involvement of the temporal lobe. 18F-FDG PET, fluorine-18 fluorodeoxyglucose positron emission tomography.

case_images: Frontotemporal dementia was suspected, and a brain 18F-FDG PET scan was performed, revealing hypometabolism in the frontal lobes, with more significant hypometabolism toward the superior orbital gyrus and inferior opercular, triangular, and opercular gyri, with less involvement of the temporal lobe (Figure 1).
