[Iatrogenic Wernicke-Korsakow syndrome with unusual neurological deficits and MRI lesions].
Wernicke-Korsakow Syndrome (WKS) is caused by thiamine (vitamin B1) deficiency and usually occurs in conjunction with chronic alcohol abuse. Our report concerns a 64-year-old, nonalcoholic, woman with no history of alcohol abuse, who became ill with WKS after 3 weeks of parenteral nourishment. As an unusual initial symptom she went blind in both eyes; this was followed a few days later by impaired consciousness and spastic tetraparesis. A cranial MRI examination showed symmetrical signal alteration (T2, FLAIR and diffusion weighting) in the medial thalamus, periaqueductal mesencephalon including the quadrigeminal plate, mamillary bodies and-most unusually-both paracentral gyri. Laboratory tests confirmed the diagnosis of WKS as significant thiamine deficiency was detected. Following several weeks of intravenous thiamine supplementation the MRI lesions were almost completely reversed but the neurological deficits regressed only partially.
