MRI head (T2-weighted; axial plane)
- of a patient with increasing memory disturbance
- Medial temporal lobe atrophy is accompanied by widening of the subarachnoid space and dilatation of the temporal horns of the lateral ventricles
- These changes have been observed in the setting of Alzheimer disease.
