Overview
In Wernicke-Korsakoff Syndrome patients, MRI may show some changes, including atrophy of mamillary bodies and hyperintense signals in the mesial dorsal thalami and periaqueductal grey matter.
MRI
In Wernicke-Korsakoff Syndrome patients, MRI may show the following changes [1]:
- Atrophy of mamillary bodies.
- Hyperintense signals in the mesial dorsal thalami
- Hyperintense signals in the periaqueductal grey matter
- On T1 C+ MRI, contrast enhancement in the aforementioned regions.
- DWI/ADC: Restricted diffusion in the same regions.
- MR spectroscopy: Reduced N-acetylaspartic acid and increased lactate concentrations.
