a A brain CT scan that was performed because of an episode of syncope 5 years before the onset of symptoms shows no atrophy (Evans’ index 0.33), but some asymmetry of the occipital horns of the lateral ventricles is apparent. b The first T1weighed MRI, which was performed 1 year after the onset of symptoms, shows the development of frontal cortical atrophy and central atrophy (Evans’ index 0.42) c with some progression over the follow-up time of 1 year (Evans’ index 0.45). d The CT control scan that was performed 6 months after shunt placement shows stable ventricular size (Evans’ index 0.45). e The coronal slice shows hippocampal atrophy (Scheltens grade 2/4) but no disproportionate obliteration of the parasagittal sulci. f The FLAIR sequence shows only minor changes in the white matter. The parasagittal images show that frontal cortical atrophy is more prominent on the right (g) compared to the left side (h)
