Coronal T2-weighted image reveals distended lateral ventricles and narrowed callosal angle. The Sylvian fissures are prominent and there is relative crowding of the gryi towards the vertex. These appearances are suggestive of Normal Pressure Hydrocephalus.
The hippocampal and temporal lobe volumes appear preserved which would be against Alzheimer disease. Huntington disease would be best assessed more anteriorly by looking for caudate head volume loss.
