Ishihara color plates utilized as an assessment for simultanagnosia in posterior cortical atrophy: A case report

Figure 1  Standard automated 30-2 perimetry shows left homonymous hemianopia.

Figure 2 18F-fluorodeoxyglucose positron emission tomography shows hypometabolism bilaterally (arrows), denser on the right. Analysis of amyloid positron emission tomography using 18F-flutemetamol showed abnormal uptake also in the posterior (occipital) cortex, with stronger signal on the right (Figure 3).

Figure 3  Amyloid 18F-flutemetamol positron emission tomography shows abnormal uptake in the occipital right cortex (arrows).
