Case 17.2

Findings

The 18F-FDG brain PET images of the brain (Fig. 17.2, top) demonstrate bilateral temporal hypometabolism consistent with dementia of Alzheimer’s type by pattern and the 18F-AV-45 PET images of brain (Fig. 17.2, bottom) demonstrate diffuse uptake in the brain with loss of gray and white matter demarcation unlike in case 1 (Fig. 17.2).
