Mamillary body enhancement in Wernicke's syndrome

Findings:
Abnormal enhancement and hyperintense signal is present in the mamillary bodies. Increased signal is present in the periaqueductal grey matter as well.

Differential Diagnosis:
No reasonable diagnosis other than thiamine deficiency.

Discussion:
Wernicke's syndrome= nystagmus, opthalmoplegia, gaze palsy, cerebellar ataxia, and confusion in association with thiamine deficiency.
mamillary bodies hyperintense on T2- also may see hyperintense periaqueductal gray and hypothalamus, may be associated atrophy of mamillary bodies.
