No sign of atrophy of the midbrain or the cerebellum.
Global cortical atrophy score (Pasquier scale): 13 – mild opening of sulci, mild ventricular enlargement.
Koedam score for parietal atrophy: 1 – mild sulcal widening, no gyral atrophy.
Mesial Temporal Atrophy: 2 – moderate widening of the choroid fissure, mild enlargement of the temporal horn and mild loss of hippocampal height.
No significant small vessel ischaemic disease.
The orbits have a normal appearance and the paranasal sinuses and mastoid air cells are clear.
No bony abnormality is seen.
