Wernicke-Korsakoff syndrome complicated by subacute beriberi neuropathy in an alcoholic patient.
2017
Thiamine (vitamin B1) deficiency is a common condition in alcohol abusers, which can lead to damage of both the peripheral and the central nervous systems. Here we describe the case of an alcoholic patient who presented with acute onset of ataxia, severe weakness of the four limbs, and hypoesthesia and dysesthesia of the distal portion of the upper and lower extremities. The clinical picture also included mental confusion and amnesia. A diagnosis of Wernicke-Korsakoff syndrome was made based on clinical symptoms and brain RMI findings. Electromyography and electroneurography revealed signs of subacute axonal sensory-motor polyneuropathy that were compatible with a rare acute presentation of…
Reversible MRI abnormalities in an unusual paediatric presentation of Wernicke's encephalopathy
1999
Background. We report an unusual paediatric presentation of acute Wernicke's encephalopathy in a 12-year-old boy affected by chronic gastrointestinal disease. MRI demonstrated, in addition to the typical diencephalic and mesencephalic signal abnormalities on T2-weighted images, enhancement of the mammillary bodies and the floor of the hypothalamus. Materials and methods. Following parenteral administration of thiamine for 4 days, the patient recovered from his neurological deficits and on follow-up enhanced MRI 1 month later, no signal abnormalities were found nor was there diencephalic or mesencephalic atrophy, as is usual in the chronic phase of the disease. Results. MRI provides crucial …
Non-alcoholic Wernicke's encephalopathy: From MRI findings of a case to differential diagnosis checklist
2018
Wernicke's encephalopathy is a serious neurological disorder secondary to thiamine deficiency in alcoholics. However, rarely it affects non-alcoholics. Here we present a case of Wernicke's encephalopathy in a non-alcoholic 56-year-old female, treated by endoscopic surgery for a duodenal ulcer two years before. She came to our attention for a sudden onset of a neurological syndrome characterized by visual deficits, diplopia, confusion, spatial disorientation and loss of short-term memory. An MRI scan showed the typical MRI findings of Wernicke's encephalopathy, which are discussed together with the possible differential diagnosis.
Magnetic resonance imaging in the assessment of brain involvement in alcoholic and nonalcoholic Wernicke's encephalopathy
2017
AIM To present the typical and atypical magnetic resonance (MR) imaging findings of alcoholic and non-alcoholic Wernicke’s encephalopathy. METHODS This study included 7 patients with Wernicke’s encephalopathy (2 men, 5 women; mean age, 52.3 years) that underwent brain MR examination between January 2012 and March 2016 in a single institution. Three patients were alcoholics and 4 patients were non-alcoholics. MR protocol included a T2-weighted sequence, a fluid attenuation inversion recovery (FLAIR) sequence, a diffusion-weighted sequence (b = 0 and 1000 s/mm2), and a contrast-enhanced MR sequence. All MR images were retrospectively reviewed at baseline and follow-up by two radiologists. RES…
