Wernicke’s encephalopathy is a rare disease, resulting from severe thiamine deficiency
(vitamin B1). Alcoholic subjects are most often affected, but it may occur outside
of this addiction.
Magnetic resonance imaging is the gold standard imaging modality to confirm the diagnosis. This pathology manifests itself in T2-weighted hyperintensity in the periaqueducal, thalami and mammillary bodies. A suitable treatment makes it possible to avoid heavy sequelae.
We report the case of a 23-year-old woman, pregnant with 12 weeks of amenorrhea, with diplopia, headache and abundant vomiting, reffering to Wernicke’s encephalopathy.
Key words: Wernicke’s encephalopathy, vitamin B1, Magnetic resonance imaging, hyperemesis gravidarum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
