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.

Selected FLAIR MRI images of the brain demonstrates hyperintensities in the periaqueductal region and the medial thalami. Case courtesy of A.Prof Frank Gaillard. ^[2]
